Question

Quizplus · Accepted Answer

Angina pectoris is typically caused by reduced blood flow to the heart muscle due to atherosclerotic plaque buildup in the coronary arteries. In some cases, vasospasm can also contribute to angina by constricting the coronary arteries and further reducing blood flow. Therefore, both vasospasm and atherosclerotic plaque can be the root cause of angina pectoris. Vasodilation and hypolipidaemia are generally not associated with angina as they do not cause significant narrowing or obstruction of the coronary arteries.
