Diastolic dysfunction (in heart failure)
Can lead to heart failure with preserved ejection fraction (HFpEF). The left ventricle loses its ability to relax normally and loses its ability to adequately fill. This impaired filling can restrict the amount of blood the heart can pump with each heartbeat and can increase the pressures within the heart chambers. The left ventricle cannot relax so the heart cannot fill with blood during the resting period. This can cause an increase in the pressures within the heart

Typically it is preferred over rate control in patients with newly diagnosed AF, who are younger than 65 years old, and who have had no previous complications when administered antiarrythmic drugs When the heart is not beating in the correct way blood is not moved correctly so, this treatment is done to put the heart back to a more regular beat and keep it at that beat as well
Transluminal valve interventions
A usually minimally invasive class of procedures which aim to open up stenotic valves by threading a catheter inside the valve and inflating a balloon or inserting a replacement valve in place of the original allowing for a higher blood flow through the heart circuit.

It is a minimally invasive surgical procedure that replaces a narrowed aortic valve that fails to open properly without removing the old, damaged valve. It instead wedges a replacement valve in place of the aortic valve. Once the new valve is expanded, it'll push the old valve leaflets out of the way and the new valve will take over the job of regulating the blood flow. A minor procedure that replaces a narrowed aortic valve without removing the other one so the blood can flow through again

Myocardial ischemia
Occurs when the blood flow through one or more of the coronary arteries is decreased, but refers specifically to a lack of oxygen to the heart muscle. It can develop slowly as arteries are blocked over time or it can occur quickly when an artery is blocked suddenly. When there is a blockage in the arteries there is a reduced blood flow, which then leads to the heart not receiving enough oxygen needed. Sudden complete blockage can lead to a heart attack.

Renal blood flow is reduced by stenosis in the renal arteries caused by atherosclerosis. It also describes the state of a reduced glomerular filtration rate, but not that of requiring a transplantation or dialysis. Patients with coronary artery disease and peripheral artery disease are at a greater risk. When plaque builds up in the kidney arteries, it causes those arteries to narrow. This reduces the amount of blood flow that the kidneys receive. When this happens, the kidneys cannot perform their proper function any more, such as removing things from the blood that the body does not need anymore.

Cilostazol
medication commonly used to treat symptoms of intermittent claudication due to peripheral vascular disease
Chronotropic response
the HR response to exercise at any stage of exercise that can be assessed by the fraction of the Heart Rate Reserve (HRR) achieved
ambulation
personal action of walking independently with or without the use of assistive devices to move, mainly by walking, from place to place
Proprioceptive neuromuscular facilitation
rehabilitation technique that stimulates the neuromuscular system through isometric contractions followed by static stretching of the selected muscle or tendon group to produce the desired movement. A rehabilitation method that uses contractions and stretching of muscles and tendons to create a patient's desired movement. Apparently, PNF has recently been applied toward coronary heart disease. https://www.ncbi.nlm.nih.gov/pubmed/30128938
Resistance vasculature
specifically arterioles and arteries, small vessels that respond to nervous stimulation and/or hormone changes in the body with dilation or constriction, and have the greatest impact on resistance to blood flow Vessels that carry oxygenated blood to the body open and close due to changes in the body and cause obstacles for blood flow
premorbid
the appearance of signs or symptoms associated with a disorder without having been formally diagnosed, or meeting only certain criteria required for clinical diagnosis and not others Being premorbid is showing symptoms of a disease or disorder before being diagnosed.
Oxygen uptake reserve
the difference between VO2 max and VO2 at rest; this method improves the accuracy of the relationship between oxygen uptake and heart rate reserve The difference between an individual's maximal oxygen usage and the amount of oxygen they use at rest
Dyspnea
the feeling of being unable to breath deeply or adequately. It is normal to occur during maximal or submaximal exertion, but hints at possible cardiac disease if it occurs while at rest or doing everyday tasks. shortness of breath
Cardiac resynchronization therapy
the insertion of electrodes in the left and right ventricles of the heart, as well as the right atrium on occasion, to treat heart failure by coordinating the function of the left and right ventricles. Wires to detect heart rate irregularities emit tiny pulses to resynchronize the heart
Denervated (heart)
the loss of afferent nerves in the myocardium, which impairs the reflex responses of the sensory endings of the cardiopulmonary region which can lead to hypotension and bradycardia related to inferior wall infarction. It casues the disappereance of neural input to the sinoatrial node and the loss of efferent and afferent nerve signaling into and out of the heart. The loss of function/ sensation in the innermost layer of muscle in the heart because of a loss of nerve impulses which can cause lower blood pressure and heart rate.
Stable angina pectoris
the most common type of angina. It exhibits a predictable pattern of chest pain at the onset of or during exercise. It occurs when the heart muscle becomes hypoxic. This usually happens because one or more of the heart's arteries is stenosed or blocked. the heart does not get enough blood because arteries are narrowing causing chest pain.
Cardiovascular disease
the most leading cause of premature death globally, in which the heart and blood vessels are restricted by abnormal lipids, smoking, hypertension, diabetes, abdominal obesity, poor diet, or irregular exercise the disease that causes the most death globally, in which the heart or cloud vessels are narrowed or blocked by large fats, smoking, high blood pressure, diabetes, excess fat in the abdominal area, poor diet, or irregular exercise
Cardiac rhythm
the predominant electrical activity of the heart, which is determined by the recording of an electrocardiogram or by the tracing evaluation of a cardiac monitor the recurring beat of the heart
Comorbidities
the presence of more than 1 distinct chronic disease or condition in an individual when an individual has 2 or more diseases
Comorbidities
the presence of more than one distinct chronic disease or condition in an individual when an individual has 2 or more diseases Typically comorbidities are strongly associated with one another or have a causal/temporal order
Prevalence
the proportion of a population that carries a disease or trait during a given time frame a specific number of people in a specific part of the world, who have a disease or illness at a given time
Myocarditis
the result of inflammation and accumulated damage to the myocardium of the heart muscle, which can lead to heart failure swelling of the middle layer of the heart muscles
Arteriolosclerosis
the thickening of small arteries and arterioles in which even small changes in wall thickness result in significant luminal compromise walls of smaller blood vessels become thicker, making a smaller tube for blood to pass through
