Systemic sclerosis, an autoimmune disease characterized by fi brosis of the skin and various internal organs, is associated with cardiovascular abnormalities including pulmonary hypertension, atherosclerosis, right and left ventricular dysfunction, arrhythmias, conduction defects, pericardial disease, and valvular heart disease. Clinicians caring for patients with this disease should regularly screen for cardiac symptoms, and patients with abnormal fi ndings should be managed in conjunction with a cardiologist to optimally modify cardiovascular risks. KEY POINTS Pulmonary hypertension is common in systemic sclerosis and carries a poor prognosis. Patients with systemic sclerosis should be screened regularly with echocardiography, followed, when necessary, by right heart catheterization to detect it early. Myocardial infarction and stroke are more common in patients with systemic sclerosis, and preventive measures are the same as for the general population. Right ventricular dysfunction secondary to pulmonary hypertension is common in systemic sclerosis; left ventricular dysfunction is less so. Routine echocardiography should include assessment of right and left ventricular function. Electrocardiography should be performed periodically, and urgently when indicated, to look for potentially dangerous arrhythmias.
