Explain why coronary artherosclerosis is such a damaging process.
Atherosclerosis the abnormal accumulation of lipid substaqnces causes a repetitive inflammatory response that alters the structure and biochemical properties of arterial walls.
Explain how cigarette smoking contributes to the development of coronary artery disease.
Cigarette smoking contributes to coronary heart disease in three ways. Smoke inhalation increases the level of blood carbon monoxide bycausing hemoglobin to combine more readily with carbon monoxide than with oxygen. Nicotinic acid triggers the release of catecholamines which raise heart rate and blood pessure and cause the coronary arteries to constrict. Smoking causes a detrimental vascular response and increases platelet adhesion increasing the probability of thrombus formation.

Variant angina
_________ objective evidence of ischemia (such as electrocardiographic changes with a stress test) but patient reports no pain.
Silent ischemia
What is angina pectoris?
It is a clinical syndrome usually characteristic by episodes or proxysms of pain or pressure in the anterior chest. The cause is insufficient coronary blood flow resulting in a decreased oxygen supply when there is increased myocardial demand for oxygen.
Describ the underlying pathophysiology that causes a normal artery to narrow because of atheroma deposits.
Arterial lemon narrowing begins with the deposit of fatty streaks (lips) on the intima (inter vessel wall) of the artery. Some develop into advance lesions as atherosclerosis advances. An inflammation response occurs and macrophages infiltrate the area ingest and transport lipids into the arterial wall. Smooth muscle cells then proliferate and form a fibrous cap around a dead fatty core. These deposits called atheromas narrow and obstruct blood flow. A ruptured plaque can from a thrombus.
An atheroma is described as"
An atheroma, also called plaque, is a fibrous cap of smooth muscle cells that form over lipid deposits within the arterial vessels protrude and narrow the lumen, and then obstruct blood flow.
A possible complication of rupture or hemorrhage of the lipid core into the plaque is?
The formation of a thrombus
A thrombus id a dangerous complication of atherosclerosis because it can lead to ____________ and ___________.
A thrombus can obstruct blood flow, cause acute myocardial infarction, or result in sudden death.
True or false?

Smoking increases CO levels and hemoglobin combines more readily with CO than with O2, thereby limiting the oxygen being supplied to the heart
True or false?

Smoking increases platelet adhesion which increases thrombus formation.
Why are calcium channel blockers helpful?
Becausee they increase myocardial oxygen supply by dilating the smooth muscle wall of the coronary arterioles, and by decreasing myocardial oxygen demands and decreasing systemic arterial pressure.
