The organic nitrates relieve angina pain by veins and coronary arteries.

A. Coronary heart disease (CHD) refers to the narrowing or blockage of the coronary arteries due to the buildup of plaque, leading to reduced blood flow to the heart muscle.

B. Cerebrovascular accident (CVA) refers to a stroke, which involves impaired blood flow to the brain rather than the heart.

C. Myocardial infarction (MI) is a heart attack, which occurs when blood flow to a part of the heart is blocked for a long enough time that part of the heart muscle is damaged or dies.

D. Angina pectoris is chest pain or discomfort caused by reduced blood flow to the heart muscle.

A. Fever and lack of muscular coordination may indicate symptoms of serotonin syndrome, a potentially serious complication that can occur when sertraline (an SSRI) is combined with lithium.

B. Nausea and headache are common side effects of sertraline and lithium but are not typically indicative of a serious complication when these medications are used together.

C. Anxiety and insomnia may be related to the underlying condition being treated (e.g., depression) but are not necessarily indicative of a serious complication.

D. Dry mouth and constipation are potential side effects of lithium but are not typically indicative of a serious complication when combined with sertraline.
