Chapter 13 TF

The main artery responsible for myocardial damage is the Left anterior descending artery.

Coronary Artery Disease was first linked to total cholesterol and triglycerides in the 1940s and 1950s.

Ventriculography is a method used to measure left ventricular function.

Atherosclerosis is primarily affected by the intima, media, and adventitia layers of the artery wall.

Clopidogrel (Plavix®) is an anticoagulant drug used in the treatment of coronary obstruction.

The presence of ischemia can be confirmed with a clinical history consistent with angina.

The Right coronary artery primarily supplies blood to the left ventricular wall.

Atherosclerosis acts as a selective barrier to prevent plasma lipid accumulation within the vessel wall.

A yellow complicated plaque is a sign of stable angina.

Myocardial ischemia occurs when there is an inadequate supply of oxygen to the heart muscle.

Stable Angina Pectoris is characterized by chest pain that is relieved promptly by exercise.

Reversible regional myocardial wall motion imaging is used in the diagnosis of stable angina.

Angina walking one or two blocks on the level at a normal pace is indicative of unstable angina.

Variant Angina Pectoris is typically triggered by physical exertion or emotional stress.

Variant Angina Pectoris is caused by coronary artery spasm leading to myocardial ischemia.

Nitroglycerin cannot reverse the reduction in coronary artery diameter associated with Variant Angina Pectoris.

Individuals with coronary atherosclerosis have a better survival prognosis compared to those with cardiac vessels that are not visible angiographically.

Silent Myocardial Ischemia only occurs in individuals with known CAD.

Crescendo angina and pain at rest are symptoms of stable angina.

Individuals with stable angina pectoris are more likely to have multivessel CAD compared to those with unstable angina.

The unstable phase is considered over when an individual's symptoms become predictable.

In very early MI presentations, serum troponin elevation can indicate coronary artery dissection.

Coronary angiography is typically more complex to perform in younger patients compared to older patients.

Most sudden cardiac deaths are caused by ventricular tachycardia.

All reversible triggers, such as acute ischemia and electrolyte abnormalities, should be addressed before electrophysiologic testing (EPS).

Isolated systolic hypertension is associated with cardiovascular disease events.

PTCA and coronary stenting in the elderly have a primary success rate lower than results known in CAD.

Exercise Stress Tests involve starting at high workloads and then progressively decreasing them.

The maximal heart rate during Exercise Stress Tests is determined by age and gender.

Blood pressure response to exercise remains the same regardless of the level of activity.

Echocardiography/Doppler studies cannot be performed during exercise.
