Heart Increased attacks of angina in coronary arteries stenosis patient

A 60 year old male diabetic has experienced angina on exertion for several years. A previous coronary angiography revealed 75% stenosis of left anterior descending coronary artery & 50% stenosis of the right coronary artery. His blood pressure is 110/80 mmhg. In the past few weeks, the frequency & severity of his anginal attacks have increased & sometimes the pain occurs even when he is lying in bed. The most likely explanation for these changes in his symptoms is
a. hypertrophy of the ischemic myocardium with increased oxygen demands
b. increased stenosis of the right coronary artery
c. fissuring of the plaque in left coronary artery with superimposed mural thrombosis
d. sudden complete thrombotic occlusion of the right & left coronary arteries
e. reduction in oxygen carrying capacity from pulmonary congestion

Default the correct answe is > C

the corrrect answer is c> fissuring of the plaque in left coronary artery with superimposed mural thrombosis ,, this patient due to the coronary arteries stenosis with less blood perfusion develops angina which was manifested as angina on exertion but recently he is developing angina even at rest which indicates unstable type of angina which most commonly occurs in patients which rupture in atheroscleotic plaque occurs with superimposed mural thrombos formation and this is very risky as the patient with unstable angina is more liable to develope MI
