Abstract

The role of primary hyperparathyroidism (PHPT) in heart disease is still somewhat uncertain in many respects. Patients with PHPT seem to have an increase in mortality and this seems mainly due to an overrepresentation of cardiovascular death. PHPT is reported to be associated with hypertension, disturbances in the renin-angiotensin-aldosterone system, cardiac arrhythmias as well as structural and functional alterations in the vascular wall. There is an increased prevalence of cardiac structural abnormalities such as LVH and functional properties of the heart may be affected by the hyperparathyroid condition as well. We report the case of a 65-year-old woman with no cardiac risk factors apart from her age and type 2 diabetes who presented in cardiogenic shock. Extensive evaluation for the aetiology of the cardiomyopathy revealed solely a diagnosis of primary hyperparathyroidism. Cardiac manifestations of primary hyperparathyroidism have been reported before but to our knowledge this is the first description of severe left ventricular function secondary to PHPT. We believe that this atypical presentation of primary hyperparathyroidism causing left ventricular cardiomyopathy warrants further attention, and that a diagnosis of primary hyperparathyroidism should always be considered in patients with systolic as well as diastolic left ventricular dysfunction, and no other obvious cause.
