Which of the following is most likely to cause left-sided congestive heart failure? -

a. incompetent tricuspid heart valve b. chronic pulmonary disease c. infarction in the right atrium d. uncontrolled essential hypertension

D:-)

D. Actually, the main reason for left heart failure isn t listed (coronary artery disease), so I ll go with D. When the blood pressure is poorly controlled, it puts increased strain on the left ventricle. Over time, this can weaken the heart muscle. All of the other answers would indicate reasons/causes of RHF.
