As late as the 1950s, elevated blood pressure was considered by many expert physicians to be necessary for the adequate perfusion of vital organs. Although the morbidity and mortality risks of hypertension were known at that time to insurance companies, which often refused life insurance policies to people with high blood pressure, there was a lag in the recognition of the dangers of hypertension in the medical community. Following the pioneering efforts of researchers who began to treat patients with malignant hypertension, the results of clinical trials and population studies, and the availability of effective antihypertensive agents, hypertension management improved rapidly. This review traces the history of hypertension management from the 1940s, when President Franklin Delano Roosevelt died of a cerebrovascular accident-a result of uncontrolled hypertension-to today, when a large number of patients, even those with less severe hypertension, are being treated successfully, with a resulting dramatic decrease in hypertension-related vascular disease.
