From the existing body of literature regarding this patient population, it is unclear why there is a higher incidence of adverse myocardial events. It may be that coronary ischemia has been missed in patients with preeclampsia. Troponin I is now readily available for detection of myocardial damage and should be used in this patient population only when clinically indicated, such as when chest discomfort or new electrocardiogram changes are observed. Patients with preeclampsia may be at higher risk for coronary events, and troponin I levels could be a valuable tool with which to monitor women who develop related symptoms.

The authors describe the case of a 72-year-old patient who has a history of rheumatic heart disease and had mitral valve replacement in childhood. She presents with progressive right-sided heart failure unresponsive to medical therapy. On evaluation she was found to have severe aortic stenosis and severe tricuspid stenosis. Surgical correction of both valves resulted in complete resolution of heart failure with remarkable improvement in quality of life. The symptoms, physical findings, and treatment options will be discussed.

The authors describe the challenging case of a 46-year-old patient who presented with a 2-week history of exertional dyspnea, paroxysmal nocturnal dyspnea, and orthopnea. He was found to have left ventricular failure and atrial fibrillation with a rapid ventricular rate. Initial work-up revealed dilated cardiomyopathy with marked left ventricular dysfunction, without any obvious cause. He received standard medical therapy for left ventricular dysfunction and his symptoms improved. Electrical cardioversion to sinus rhythm and maintenance resulted in complete recovery of left ventricular function within 6 months. (c)2001 CHF, Inc.
