To determine whether the use of non-potassium-sparing diuretics and β-blockers is associated with an excess risk for sudden cardiac death in hypertensive patients.
Rotterdam, the Netherlands.
257 case-patients who had died suddenly while receiving drug therapy for hypertension and 257 living controls also receiving drug therapy for hypertension.
Detailed information on medication use and clinical characteristics of all case-patients and controls was collected from the files of general practitioners. Additional information on medication use was obtained from computerized pharmacy records.
Patients receiving non-potassium-sparing diuretics had an increased risk for sudden cardiac death (relative risk, 1.8 [95% CI, 1.0 to 3.1]) compared with a reference group treated primarily with potassium-sparing diuretics. The corresponding relative risk for β-blocker use was 1.7 (CI, 1.1 to 2.6). The use of non-potassium-sparing diuretics without β-blockers was associated with a higher risk for sudden death (relative risk, 2.2 [CI, 1.1 to 4.6]) than was concomitant use of non-potassium-sparing diuretics and β-blockers (relative risk, 1.4 [CI, 0.6 to 3.0]). The risk for sudden cardiac death among recipients of non-potassium-sparing diuretics was more pronounced in those who had been receiving the diuretic for less than 1 year and in those aged 75 years or younger.
The use of non-potassium-sparing diuretics and β-blockers is associated with an increased risk for sudden cardiac death. This association may offset part of the mortality benefit of these drugs in the treatment of hypertension.
