title: Increased prevalence of coronary heart disease in analgesic nephropathy: relation to hypertension, hypertriglyceridemia and combined hyperlipidemia.
abstract: The prevalence of coronary heart disease (58%) in 43 patients with analgesic nephropathy with moderate to severe chronic renal failure was significantly higher than in the general population of the same age and sex. Mean serum triglyceride concentration and mean diastolic blood pressure were significantly higher in the group with coronary heart disease (214 mg/dl and 102 mm Hg, respectively) than in the group without it (162 and 94). Serum triglyceride values correlated inversely with GFR, indicating that hypertriglyceridemia was largely due to associated chronic renal failure; a specific effect of analgesic abuse on prevalence of heart disease, noted by others, could not be assessed in the absence of GFR-matched controls. The prevalence of coronary heart disease was significantly higher (81%) in the group with combined hyperlipidemia (hypertriglyceridemia and hypercholesteremia) compared to the groups without it or with normal serum triglyceride concentrations (44 and 41%, respectively). Hypotryptophanemia (a possible cause of hyperlipidemia in the nephrotic syndrome) was present in 77% of patients.
