a 22-year-old male is brought to the emergency room after sustaining a stab wound in the chest. He reports shortness of breath. On physical examination, his vital signs are a temperature of 37 C, heart rate 121 bpm, blood pressure 90/60 mmHg, respiratory rate 20 rpm, and oxygen saturation 99% on room air. Physical examination is significant for muffled heart sounds and a drop of BP > 10 mm Hg systolic with inspiration. You note his neck veins are distended. He does not respond to aggressive fluid resuscitation. You order a chest x-ray and the EKG reveals low voltage QRS complexes and electrical alternans.
Cardiac Tamponade
a 64-year-old female who reports five weeks of occasional shortness of breath and pain radiating from the shoulder to the chest. The patient reports that the pain is worse with inspiration and lying down and is relieved by sitting forward. On physical exam you note distant heart sounds. Her EKG shows low voltage QRS complexes and electrical alternans.
Pericardial Effusion
a 25-year-old male who presents to the clinic complaining of mild dyspnea on exertion. Examination reveals a prominent jugular pulsation and a palpable parasternal lift. There is a harsh systolic murmur best heard at the second and third left intercostal space; it radiates to the left shoulder. An early systolic sound precedes the murmur during expiration. ECG demonstrates right-axis deviation
Pulmonary Stenosis

4-year-old boy who is brought to your office by his parents because he gets tired very easily and cannot keep up with the other children. On exam, you hear a loud, harsh, holosystolic murmur at the left lower sternal border without radiation to the axillae.
Ventricular Septal Defect
A 10-month-old girl was admitted to the hospital for cardiac catheterization. Her history included cyanosis noted at about 6 weeks of age, increasing over the last 7 months and becoming more severe with crying or physical activity. The chest x-ray demonstrates a "boot shaped heart" A presumptive diagnosis of tetralogy of Fallot (TOF) was made on admission. TOF has 4 components, which of the following below is not part of the diagnosis? A. Pulmonary Valve Stenosis B. VSD C. overriding aorta D. RVH E. ASD
ASD
a 48-year-old male with type I diabetes mellitus and end-stage renal disease currently on hemodialysis with dyspnea, cough and chest pain. He describes the pain as worse during inspiration and when he is lying on his back. The patient reports significant relief oh his chest pain with sitting up or leaning forward. A basic metabolic panel is remarkable for a BUN > 60 mg/dL. On cardiac auscultation, you hear a pericardial friction rub that is heard best when the patient is upright and leaning forward. The EKG (seen here) demonstrates diffuse, ST-segment elevations in the precordial leads.
Acute Pericarditis
Which of the following is the chief adverse effect of thiazide diuretics? A. Hypokalemia B. Hypernatremia C. Hypocalcemia D. Hypermagnesemia
Answer = A Thiazide diuretics can induce electrolyte changes. Principle among those is hypokalemia.
Annual blood pressure determinations should be obtained beginning at the age of A. 3 years. B. 5 years. C. 12 years. D. 18 years
Answer = A 3 yo In 2013, the United States Preventive Services Task Force (USPSTF) concluded that there was inadequate evidence to support BP screening in asymptomatic children and adolescents to prevent subsequent cardiovascular disease (VCD). However, the measurement of BP is a readily available, noninvasive procedure in office settings and that it should remain a routine part of comprehensive clinical care of children and adolescents as noted by the 2017 AAP guidelines for high blood pressure (BP) in children and adolescents, which are endorsed by the American Heart Association (AHA). They recommend that periodic measurements of blood pressure should be part of routine preventive health assessments beginning at the age of 3 years.
A 49-year-old female presents complaining of several episodes of chest pain recently. Initial ECG in the emergency department shows no acute changes. Two hours later, while the patient was having pain, repeat electrocardiogram revealed ST segment elevation in leads II, III, and AVF. Cardiac catheterization shows no significant obstruction of the coronary arteries. Which of the following is the treatment of choice in this patient? A. Nifedipine (Procardia) B. Metoprolol (Lopressor) C. Lisinopril (Zestril) D. Carvedilol (Coreg)
Answer = A Nifedipine This patient is most likely having coronary artery spasm. This can be treated prophylactically with calcium channel blockers such as nifedipine.
60-year-old male is brought to the ED complaining of severe onset of chest pain and interscapular pain. The patient states that the pain feels as though "something is ripping and tearing". The patient appears shocky; the skin is cool and clammy. The patient has an impaired sensorium. Physical examination reveals a loud diastolic murmur and variation in blood pressure between the right and left arm. Based on this presentation what is the most likely diagnosis? A. Aortic dissection B. Acute myocardial infarction C. Cardiac tamponade D. Pulmonary embolism
Answer = Aortic dissection The scenario presented here is typical of an ascending aortic dissection. In an acute myocardial infarction the pain builds up gradually. Cardiac tamponade may occur with a dissection into the pericardial space; syncope is usually seen with this occurrence. Pulmonary embolism is usually associated with dyspnea along with chest pain.
64 year-old patient with known history of type 1 diabetes mellitus for 50 years has developed pain radiating from the right buttock to the calf. Patient states that the pain is made worse with walking and climbing stairs. Based upon this history which of the following would be the most appropriate test to order? A. Venogram B. Arterial duplex scanning C. X-ray of the right hip and L/S spine D. Venous Doppler ultrasound
Answer = Arterial duplex scanning Given the patient's long history of type 1 diabetes mellitus the patient most likely has vascular occlusive disease. Evaluation of arterial blood flow is assessed using the duplex scanner. X-ray of the L/S spine and right hip while not harmful may give information regarding bony structures. Venous Doppler ultrasound will not give information of arterial perfusion.
A 63 year-old female presents with a complaint of chest pressure for one hour, noticed upon awakening. She admits to associated nausea, vomiting, and shortness of breath. 12 lead EKG reveals ST segment elevation in leads II, III, and AVF. Which of the following is the most likely diagnosis? A. Aortic dissection B. Inferior wall myocardial infarction C. Acute pericarditis D. Pulmonary embolus
Answer = B Myocardial infarction often presents with chest pressure and associated nausea and vomiting. ST segment elevation in leads II, III, and AVF are classic findings seen in acute inferior wall myocardial infarction.
You are asked to evaluate a term infant in the delivery room. He was born a few minutes earlier by spontaneous vaginal delivery with Apgar scores of 9 and 9. The mother had good prenatal care and a normal pregnancy. No significant family history is noted. On physical examination, the infant appears alert and is active and crying. Acrocyanosis is noted on extremities. A grade 2/6 soft, systolic murmur is audible at the left upper sternal border. Otherwise, the examination is completely normal. What should be your next step in the management of this patient? A. order an echo B. perform a second detailed physical exam at 24 hours C. order an EKG and CXR D. get a cardiology consult
Answer = B This is the transient systolic murmur of patent ductus arteriosus. It is audible at the upper left sternal border and in the left infraclavicular area on the first day, and it usually disappears soon thereafter. As in older infants and children, not all heart murmurs in neonates are pathologic. More than 50% of term-born infants are found to have innocent systolic murmurs at some time during the first week of life. The prevalence is even higher in premature infants. The incidence of structural congenital heart disease is estimated to be less than 1% of all live births. The infant should have a detailed examination at 24 hours and again before discharge before any further decisions are made. Acrocyanosis, a normal phenomenon, should also be distinguished from central cyanosis.
55 year-old male is seen in follow-up for a complaint of chest pain. Patient states that he has had this chest pain for about one year now. The patient further states that the pain is retrosternal with radiation to the jaw. "It feels as though a tightness, or heaviness is on and around my chest". This pain seems to come on with exertion however, over the past two weeks he has noticed that he has episodes while at rest. If the patient remains inactive the pain usually resolves in 15-20 minutes. Patient has a 60-pack year smoking history and drinks a martini daily at lunch. Patient appears overweight on inspection. Based upon this history what is the most likely diagnosis? A. Acute myocardial infarction B. Prinzmetal variant angina C. Stable angina D. Unstable angina
Answer = D Pain in unstable angina is precipitated by less effort than before or occurs at rest
Cardiac tamponade is potentially life-threatening. What is the mechanism by which the effusion impedes stroke volume? A. direct compression increases end-diastolic volume B. increased pressure in pericardium decreases coronary blood flow C. increased pressure decreases sinus rhythm D. compression of inferior vena cava decreases preload
Answer = D compression of inferior. vena cava decreases preload Compression caused by cardiac tamponade decreases the preload, which is an important component of stroke volume. Direct compression prevents inflow of blood to the heart muscle, which will decrease the end-diastolic volume. While tamponade does increase the pressure in the heart muscle itself, stroke volume is the amount of blood that is ejected with each contraction. The increased intracardiac pressure associated with tamponade affects the patient's cardiac output. Tamponade has no intrinsic effect on the heart rate.
A 52-year-old male with history of hypertension and hyperlipidemia presents with an acute myocardial infarction. Urgent cardiac catheterization is performed and shows a 90% occlusion of the left anterior descending artery. The other arteries have minimal disease. Ejection fraction is 45%. Which of the following is the treatment of choice in this patient? A. Coronary artery bypass grafting (CABG) B. Streptokinase C. Percutaneous coronary intervention (PCI) D. Warfarin (Coumadin)
Answer = PCI Immediate coronary angiography and primary percutaneous coronary intervention have been shown to be superior to thrombolysis.
64 year-old male, with a long history of COPD, presents with increasing fatigue over the last three months. The patient has stopped playing golf and also complains of decreased appetite, chronic cough and a bloated feeling. Physical examination reveals distant heart sounds, questionable gallop, lungs with decreased breath sounds at lung bases and the abdomen reveals RUQ tenderness with the liver two finger-breadths below the costal margin, the extremities show 2+/4+ pitting edema. Labs reveal the serum creatinine level 1.6 mg/dl, BUN 42 mg/dl, liver function test's mildly elevated and the CBC to be normal. Which of the following is the most likely diagnosis? A. Right ventricular failure B. Pericarditis C. Exacerbation of COPD D. Cirrhosis
Answer = Right ventricular failure Signs of right ventricular failure are fluid retention i.e. edema, hepatic congestion and possibly ascites.
Which of the following is the most common etiology for a subarachnoid hemorrhage? A. Trauma B. Ruptured aneurysm C. Bleeding arteriovenous malformation D. Embolic stroke E. Primary intracerebral hemorrhage
Answer = Ruptured aneurysm Up to 80% of subarachnoid hemorrhages can be attributed to the rupture of saccular or berry aneurysms in nontraumatic subarachnoid hemorrhages. Most of these aneurysms arise from the anterior circulation. Most are in the anterior communicating artery. Twenty-five percent of patients will have more than one aneurysm. Because of cerebrovascular anatomy, the blood is usually confined to the subarachnoid space. Blood from a ruptured arteriovenous malformation can be intraparenchymal and cause focal neurologic symptoms. Trauma is more likely to cause epidural or subdural hematoma.
Which of the following is a cause of high output heart failure? A. myocardial ischemia B. complete heart block C. aortic stenosis D. thyrotoxicosis
Answer = Thyrotoxicosis High output heart failure occurs in patients with reduced systemic vascular resistance. Examples include: thyrotoxicosis, anemia, pregnancy, beriberi and Paget's disease. Patients with high output heart failure usually have normal pump function, but it is not adequate to meet the high metabolic demands.
A 55 year-old male is seen in follow-up for a complaint of chest pain. Patient states that he has had this chest pain for about one year now. The patient further states that the pain is retrosternal with radiation to the jaw. "It feels as though a tightness, or heaviness is on and around my chest". This pain seems to come on with exertion however, over the past two weeks he has noticed that he has episodes while at rest. If the patient remains inactive the pain usually resolves in 15-20 minutes. Patient has a 60-pack year smoking history and drinks a martini daily at lunch. Patient appears overweight on inspection. Based upon this history what is the most likely diagnosis? A. Acute myocardial infarction B. Prinzmetal variant angina C. Stable angina D. Unstable angina
Answer = Unstable angina Pain in unstable angina is precipitated by less effort than before or occurs at rest
A 45-year-old obese Caucasian gentleman arrives at your clinic for a routine check-up after having some blood work done during a workplace health screening. He is found to have an LDL cholesterol level of 720 mg/dL. He states that his father and brother had high cholesterol and both died at a young age from a heart attack. He has a follow-up appointment with his cardiologist because of some occasional chest pain and abnormalities seen on his EKG. Additionally, you notice that he has well-demarcated yellow deposits around his eyes. He is started on high dose statin and his LDL at 12 weeks is 350 mg/dL. What is the next best step in this patient's management? A. Continue high dose statin, the patient's LDL is at goal B. Add niacin 100 mg three times daily C. Add ezetimibe 10 mg daily D. Add a PCSK9 inhibitor E. Refer to a lipid specialist
Answer = add ezetimibe Familial hypercholesterolemia (FH) is the most common autosomal dominant genetic disease. The clinical syndrome (phenotype) is characterized by extremely elevated levels of low-density lipoprotein cholesterol (LDL-C) and a propensity to early-onset atherosclerotic cardiovascular disease. In general, homozygotes manifest the disease at a much earlier age than heterozygotes and the disease is more severe. Homozygous FH patients are rare and have an estimated prevalence of approximately 1:300,000 to 1:400,000. Heterozygous FH is estimated to occur in 1 in 200 to 250 individuals in the United States. The blood cholesterol level for patients homozygous for familial hypercholesterolemia is usually above 700 mg/dL. The diagnosis of heterozygous familial hypercholesterolemia (FH) is made with genetic testing or clinical criteria. A causative mutation in the LDLR, APOB, or PCSK9 gene(s) secures this diagnosis. When genetic testing is not available or not felt to be necessary, you can use the Dutch Lipid Clinic Network criteria, which assigns points based on low density lipoprotein cholesterol (LDL-C) levels, personal history of early atherosclerotic cardiovascular disease (ASCVD), family history of early ASCVD, or high cholesterol in a first-degree relative, and personal and physical examination finding If LDL-C is not at goal after 6-12 weeks on a high dose statin the next best step for the treatment of familial hypercholesterolemia is to add ezetimibe 10 mg daily and check again in 6-12 weeks. If at that time the patient's LDL is still not at goal (ideally < 150) refer to lipid specialist to consider adding a PCSK9 inhibitor
What is (are) the drug( s) of choice for the treatment of isolated hypertriglyceridemia? A. nicotinic acid B. gemfibrozil C. lovastatin D. a and b E. all of the above
Answer = gemfibrozil The drug of choice for most cases of hypertriglyceridemia is gemfibrozil or another fibric acid derivative. Hypertriglyceridemia may be associated with type IIa, type IIb, type III, or type IV hyperlipoproteinemia. The usual dose of gemfibrozil is 0.6 g twice a day. Gemfibrozil will decrease hypertriglyceridemia by 40% to 80% and will potentially increase HDL by 10% to 20%. Combining a reductase inhibitor with gemfibrozil has become a commonly used regimen, although it was once feared. This combination still should be used with caution and may be tolerated if a low dose of one drug is given 6 to 12 hours apart from a low dose of the other (e.g., pravastatin, 10 to 20 mg in the morning, with gemfibrozil, 600 mg in the evening). This dosing regimen may, however, limit the effectiveness of this option. Laboratory monitoring of this therapeutic option is necessary and with vigilance because of an increase in both hepatic and myopathic side effects. In high-risk patients, these risks are frequently outweighed substantially by the cardiac risk factor reduction.
58 year-old male who is otherwise healthy presents with chest pain and is found to have left main coronary artery stenosis of 75%. The most important aspect of his management now is A. daily aspirin to prevent MI. B. nitrate therapy for the angina. C. aggressive risk factor reduction. D. referral for coronary artery revascularization
Answer = referral for CA revascularization Although medical therapy is important, revascularization is indicated when stenosis of the left main coronary artery is greater than 50%.
Which of the following is an absolute contraindication to thrombolytic therapy in a patient with an acute ST segment elevation myocardial infarction? A. history of severe hypertension presently controlled B. current use of anticoagulation therapy C. previous hemorrhagic stroke D. active peptic ulcer disease
Answer C = previous hemorrhagic stroke Absolute contraindications to thrombolytic therapy include a previous hemorrhagic stroke, a stroke within one year, a known intracranial neoplasm, active internal bleeding, and a suspected aortic dissection. Severe, but controlled hypertension, use of anticoagulation, and active peptic ulcer disease are relative contraindications in which the risk/benefit ratio must be weighed in each patient.
Which of the following should be avoided in patients with heart failure? A. Diuretics B. Digoxin C. Anticoagulants D. Calcium channel blockers
Answer D = CCB The ACC/AHA guidelines advise that nonsteroidal anti-inflammatory drugs (NSAIDs), calcium channel blockers, and most antiarrhythmic agents may exacerbate heart failure and should be avoided in most patients. NSAIDs can cause sodium retention and peripheral vasoconstriction and can attenuate the efficacy and enhance the toxicity of diuretics and ACE inhibitors.

Three days later, 4/4 blood cultures grow Streptococcus viridans that is highly sensitive to penicillin.
Bacterial endocarditis
48 year-old male with a history of coronary artery disease and two myocardial infarctions complains of shortness of breath at rest and 2-pillow orthopnea. His oxygen saturation is 85% on room air. The patient denies any prior history of symptoms. The patient denies smoking. Results of a beta-natriuretic peptide (BNP) are elevated. What should be your next course of action for this patient? A. Send him home on 20 mg furosemide (Lasix) p.o. every day and recheck in one week B. Send him home on clarithromycin (Biaxin) 500 mg p.o. BID and recheck in 1 week C. Admit to the hospital for workup of left ventricular dysfunction D. Admit to the hospital for workup of pneumonia
C. Admit to the hospital for workup of left ventricular dysfunction An elevated BNP is seen in a situation where there is increased pressure in the ventricle during diastole. This is representative of the left ventricle being stretched excessively when a patient has CHF. Sending a patient home would be inappropriate in this case.
A 63 year-old male with history of hypertension and tobacco abuse presents complaining of dyspnea on exertion for two weeks.

A patient is diagnosed with VSD, at this time the infant should A. have immediate cardiac Cath performed, followed by surgical closure within 3 months B. immediate surgery C. be managed with digoxin and diuretics D. none of the above
D = none of the above Watchful expectation should be pursued. The prognosis is excellent, and the defect will probably close spontaneously. As the VSD becomes smaller, the murmur becomes shorter and maintains its regurgitant characteristics (i.e., it starts off with the first heart sound). Spontaneous closure occurs in 30% to 40% of cases, even more frequently in small defects. Pediatric cardiology referral is appropriate for serial examinations and echocardiograms. Infants with a large VSD who develop congestive heart failure and growth retardation should be treated first with digoxin and diuretics. If this fails, surgical intervention is necessary within the first 6 months of life.
A 58 year-old male who is otherwise healthy presents with chest pain and is found to have left main coronary artery stenosis of 75%. The most important aspect of his management now is A. daily aspirin to prevent MI. B. nitrate therapy for the angina. C. aggressive risk factor reduction. D. referral for coronary artery revascularization
D. Referral for CA revas Although medical therapy is important, revascularization is indicated when stenosis of the left main coronary artery is greater than 50%.
A 50-year-old male with history of alcohol abuse presents with complaint of worsening dyspnea. Physical examination reveals bibasilar rales, elevated jugular venous pressure, an S3 and lower extremity edema. Chest x-ray reveals pulmonary congestion and cardiomegaly. Electrocardiogram shows frequent ventricular ectopy. Echocardiogram shows left ventricular dilatation and an ejection fraction of 30%. Which of the following is the most likely diagnosis in this patient?
Dilated CMP
Young adult presents with one week of fatigue, worsening SOB, swelling in feet & ankles. PMH unremarkable except for recent cold 2 weeks prior to this. Temp 98.6, BP 120/70, pulse 84, RR 20. Physical exam notable for bibasilar crackles, jugular venous distension, an S3 gallop (heard below), and 2+ pitting edema up to the ankles bilaterally. CXR reveals cardiomegaly with pulmonary congestion and echocardiography demonstrates left ventricular dilation and dysfunction and low cardiac output.
Dilated CMP
A 58-year-old man presents to your office 4 weeks after being hospitalized for MI. He is complaining of chest pain, fever, and multiple joint pain. Laboratory tests do not show an increase in cardiac enzymes. The most likely diagnosis is A. Dressler's syndrome B. Costochondritis C. Meigs' syndrome D. Recurrent MI E. Pneumonia
Dressler's syndrome, or postmyocardial infarction syndrome, occurs several days to several weeks after MI. The condition is characterized by chest pain, fever, pericarditis with a pericardial friction rub, pericardial effusion, pleurisy, pleural effusions, and multiple joint pain. The cause is thought to be an autoimmune response to the damaged myocardial tissue and pericardium. The difference between Dressler's syndrome and recurrent MI is difficult to determine; however, in Dressler's syndrome, there is minimal or no increase in cardiac enzymes. Treatment includes the use of aspirin, NSAIDs, and, in some cases, corticosteroids.

A Metoprolol (Lopressor) B. Cozaar C. Lisinopril (Zestril) D. Hydrochlorothiazide (Diuril)
Metoprolol. Beta blockers are initial drug of choice in a symptomatic pt w. hypertrophic CMP. Avoid nitrates and other drugs that decrease preload (diuretics, ACE, ARBs) because these decrease LV size and worsen LV function
a 64-year-old obese man with a history of hyperlipidemia and poorly controlled type 2 diabetes underwent percutaneous transluminal coronary angioplasty of the posterior descending artery 3 days ago for an ST-elevation myocardial infarction. He has so far been stable since this procedure, but overnight you are called to his bedside. He is pallid and breathing laboriously. Notable vital signs include a blood pressure of 85/45 mmHg with a heart rate of 125 beats per minute. His lung exam is notable for bibasilar crackles.

Mitral Regurg
Which of the following American College of Cardiology (ACC) and American Heart Association (AHA) stages do the majority of patients with heart failure fall under? A. Stage A B. Stage B C. Stage C D. Stage D
Most patients with heart failure are in stage C. ACC/AHA stage C patients have structural heart disease and current or previous symptoms of heart failure; ACC/AHA stage C corresponds with New York Heart Association (NYHA) class II and III heart failure. Drugs routinely used in these patients include ACE inhibitors/angiotensin receptor blockers, beta-blockers, and loop diuretics for fluid retention. For selected patients, therapeutic measures include aldosterone receptor blockers, hydralazine and nitrates in combination, and cardiac resynchronization with or without an implanted cardiac device.

The most common cause of nontraumatic cardiac tamponade is metastatic malignancy. Common symptoms include dyspnea and profound exercise intolerance. Physical examination findings include tachycardia, low systolic arterial BP with a narrow pulse pressure, and pulsus paradoxus. Less common causes of nontraumatic tamponade include acute or chronic idiopathic pericarditis, uremia, bacterial or tubercular pericarditis, hemorrhage (from anticoagulant use), systemic lupus erythematosus, radiation treatments, and myxedema.
Which is the most common pathologic murmur? A. ASD B. VSD C. patent ductus arteriosus D. MVP
The most common pathologic cardiac murmur in childhood is VSD. With a VSD, the cardiac murmur is often not present at birth but is first heard at the 2- to 4-week well-baby checkup. As discussed previously, the most common outcome of this congenital heart defect is spontaneous closure. In some cases, however, surgical closure is indicated. The most uncommon scenario is the development of congestive cardiac failure secondary to VSD. The relative frequencies of pathologic cardiac murmurs in childhood are as follows: VSD, 38%; ASD, 18%; pulmonary valve stenosis, 13%; pulmonary artery stenosis, 7%; aortic valve stenosis, 4%; patent ductus arteriosus, 4%; mitral valve prolapse, 4%; and all others, 11%.
2-week-old infant is brought to your office by his mother for a checkup and establishment of care. They have just moved into the area, and you have not seen the baby before. The mother states that the baby was born at term and she had a normal pregnancy. On examination, the infant has a grade 3/6 harsh pansystolic heart murmur heard along the lower left sternal edge. There is no radiation of the murmur. The heart rate is 82 beats/minute and regular. There is no thrill. The blood pressure is 80/60 mm Hg. No other abnormalities are found on examination. The infant is in the 50th percentile for height and weight. What is the most likely cardiac diagnosis in this infant? VSD, Innocent cardiac murmur, tetralogy of Fallot, pulmonary atersia or coarctation of aorta
This infant most likely has a small VSD. Most commonly, the murmur is detected at 2 to 6 weeks of age when the infant returns for the initial checkup after hospital discharge. The typical heart murmur associated with a VSD is harsh, pansystolic, and best heard at the lower left sternal edge. Even as the VSD becomes smaller, it maintains its regurgitant characteristic of starting off with the first heart sound (holosystolic timing). As a VSD closes and becomes smaller, the murmur can actually become louder until the VSD is closed. Infants with small VSDs are well developed and acyanotic. Infants with large VSDs may have poor weight gain or show signs of congestive heart failure before 2 or 3 months of age.
68 year-old female comes to the office for an annual physical examination. Her past medical history is significant for a 40-pack year cigarette smoking history.
