The overall cardiovascular mortality in patients with chronic renal failure is about 30 per cent of which 10 per cent is attributed to myocardial infarction. This prevalence led some workers to propose a hypothesis of "accelerated atherosclerosis" due to the hyperlipidaemia observed in 30 to 70 per cent of patients. However, the concept of accelerated atherosclerosis, which was based essentially on clinical studies, has been questioned. Pericardial effusion is a common complication of chronic renal failure and has been reported in over 62 per cent of patients in echocardiographic studies. There are many causes and symptoms are often mild; systematic echocardiographic examination of patients with renal failure undergoing haemodialysis has shown 32 per cent of pericardial effusions to be asymptomatic. There are two potential complications: cardiac tamponade and, lesser frequently, constrictive pericarditis. Cardiac failure is a common cause of death in patients undergoing long-term dialysis. The myocardial histological appearances are those of fibrosis, the etiology of which is not fully understood although the dialysis membranes and hypotensive episodes occurring during haemodialysis have been thought to play a role. Left ventricular hypertrophy and fibrosis may give rise to ventricular arrhythmias which could explain some of the cases of sudden death observed in patients with renal failure and often wrongly attributed to ischemic heart disease. Another form of myocardial disease which is observed later is characterised by an alteration of systolic function with left ventricular dilatation and hypokinesia and increased end diastolic pressures without an increase in left ventricular wall thickness. Valvular heart disease may also result from renal failure.(ABSTRACT TRUNCATED AT 250 WORDS)

Myocardial rupture is a rare complication of acute myocardial infarction (MI), usually presenting with chest pain. The most common site of rupture is the anterior wall. Myocardial rupture presents similar to cardiac tamponade, most frequently as cardiogenic shock. Many clinical conditions, however, present similarly. The differential diagnosis should include myocardial rupture if clinical suspicion is high. This report describes a 77-year-old man with a medical history putting him at significant risk for coronary artery disease status, including a coronary artery bypass graft, chronic kidney disease stage 3, and hyperlipidemia. He presented at the ED for worsening shortness of breath and feeling unwell. Transthoracic echocardiography revealed an anterior, anterolateral akinesis, a ventricular septal defect, and free wall rupture. Myocardial rupture is an acute cardiac emergency; a high level of clinical suspicion may help in detecting this rare manifestation of acute MI.
