Age and cause of death in mitochondrial diseases.
We report on the age and the causes of death in 16 patients with mitochondrial diseases. Nine patients with mitochondrial encephalomyopathy, lactic acidosis, and stroke-like episodes (MELAS) died at a mean age of 34 years and three patients with chronic progressive external ophthalmoplegia at a mean age of 56 years. The causes of death were cardiopulmonary failure (n = 5), status epilepticus (n = 4), aspiration pneumonia (n = 2), pulmonary embolism (n = 2), renal failure (n = 1), metabolic disturbance (n = 1), and unknown causes (n = 1). Thus, many patients in this series died of medical complications, some of which may be prevented.
