You are treating a 63-year-old man for diabetes (non-insulin dependent), high cholesterol, and hypertension. He is single and works as a clerk in a doctor's office. The patient tells you that, this winter, he has been experiencing episodes of "burning and pressure-type" chest pain 2 or 3 times per week; episodes last for about 3 to 10 minutes, and they are usually relieved by resting. The episodes generally occur after lunch when he takes a "cigarette break with a friend." He had attributed these episodes to cold weather or tension, but he then became really concerned last week when pain occurred while he was climbing stairs. He then became breathless, nauseated, and started sweating. His father died in his forties because of a "heart condition." You conclude that the patient has all risk factors for myocardial ischemia (cigarette smoking, diabetes, high cholesterol, hypertension, sedentary lifestyle, and family history of premature heart disease) and classic provocative factors for angina pectoris (pain after a meal, cold weather, anxiety). You decide to treat him with nitroglycerin, an antianginal drug. This treatment causes vasodilatation by producing what signal molecule? A Nitric oxide B Nitrous oxide C Nitrogen dioxide D Epinephrine E Verapamil

A

You examine the ECG trace on a 47-year-old woman that you suspect may have a myocardial infarction. The P wave looks normal, and the PR interval is shortened. She is experiencing runs of 3 or more PVCs. You understand that the SA node is the pacemaker of the heart, although the A-V nodal fibers, bundles of His, and Purkinje fibers also have an intrinsic rhythmicity. What best describes why the SA node is the heart's natural pacemaker? A It depolarizes and repolarizes at regular intervals unlike those of the A-V node, bundles of His, or the Purkinje fibers. B It sends stronger action potentials, overriding those of the A-V node, bundles or His, and the Purkinje fibers. C The A-V node, bundles of His, and Purkinje fibers only begin to depolarize if the sinus node fails. D The A-V node, bundles of His, and Purkinje fibers depolarize weakly and are not strong enough to initiate contraction of cardiac muscle. E It repolarizes more slowly than the A-V node, bundles of His, or Purkinje fibers.

A

A 13-year-old girl is 74 inches (1.88 m) tall. She has had no major medical illnesses, but on review of systems, she reports joint laxity and a history of dental crowding. Her family history is significant for her mother also being tall and having a history of retinal detachment. Her maternal uncle died at the age of 33 due to a ruptured thoracic aortic aneurysm. On physical examination, you note a narrow high-arched palate, pectus carinatum, high-pitched decrescendo diastolic murmur at the left sternal border, arachnodactyly, and an increased arm span to height ratio. What is the most likely diagnosis? A Ehlers Danlos syndrome B Marfan syndrome C Noonan syndrome D Klinefelter syndrome E Turner syndrome

B

You acknowledge these concerns, and during the physical examination, you note severe tachypnea, bounding peripheral pulses, and a rough, machinery murmur that is auscultated best near the 2nd left intercostal space. What is the most likely diagnosis? A Atrioventricular septal defect B Patent ductus arteriosus C Coarctation of the aorta D Ventricular septal defect E Still murmur

B

A 25-year-old man presents after experiencing pronounced shortness of breath while at the gym. You cannot obtain satisfying information from him during the interview and you think that he might be mentally challenged. On examination he appears short for his age and you notice webbed neck, dental malocclusion, antimongoloid slanting of the eyes, and hypogonadism. Auscultation reveals high-pitched systolic ejection murmur maximal in the second left interspace with radiation to the left shoulder and ejection click that decreases with inspiration. His second heart sound (P2) is delayed and soft. The impulse of right ventricle is increased, and you palpate a thrill at second left intercostal space. What will be your best next diagnostic step? A Mental retardation assessment B Echocardiography/Doppler C Cardiac catheterization D Cardiac MRI E Karyotyping

B

A 25-year-old woman presents with intermittent palpitations that are associated with lightheadedness; she admits to a past medical history of having a self-described "hole in her heart". These seem to occur upon significant exertion and when she is "stressed out." She denies chest pain, shortness of breath, wheezing, hemoptysis, cough, syncope, abdominal pain, rashes, peripheral edema, diaphoresis, and vomiting. Her physical exam is remarkable for a mid-to-late systolic click; it is followed by a high-pitched, 'whooping' late systolic crescendo-decrescendo murmur, and it is heard best at the apex. The click occurs earlier with standing and upon Valsalva strain, and it also occurs later in the cardiac cycle with squatting and sustained handgrip. What is the most likely diagnosis? A Aortic stenosis B Mitral valve prolapse C Ventricular septal defect D Aortic regurgitation E Mitral stenosis

B

A 36-year-old woman presents with fatigue, breathlessness, and abdominal discomfort and swelling. The onset of symptoms was gradual. She is experiencing prominent pulsations in the neck. She also gives a history of pharyngitis caused by Streptococcus during her childhood. Physical examination reveals raised jugular venous pulsations and prominent a waves. Extremities show presence of 2+ edema, and abdominal examination reveals a positive fluid thrill. Cardiac examination shows a prominent right atrium on palpation to the right of the sternum. Auscultation reveals a tricuspid opening snap with a diastolic murmur heard along the left sternal border, which increases with inspiration. The first heart sound is split widely. Diagnostic studies reveal an enlarged right atrium on chest X-ray. There is right atrial enlargement and valvular structural deformity in the tricuspid area. What is the pathophysiological cause of the fluid thrill seen in the abdomen in this patient? A Seeding of the peritoneum by rheumatic vegetations from the tricuspid valve, leading to inflammation of the peritoneum and effusion B Increase in the right atrial pressure causes venous congestion and forms ascites C Myxoma of the right atrium leading to back-flow pressure and ascites D Congenital tricuspid stenosis leading to obstructed venous flow, back flow pressure, and ascites E Tuberculosis of the peritoneum and pericardium leading to cardiologic manifestation and ascites
