[Importance of hypertension in patients after the first stroke: retrospective cohort study].

Background and Objectives: Hypertension (HT) is a key risk factor for stroke. We evaluated whether the importance of hypertension on the risk of ischemic stroke has increased in recent decades.
Methods: Retrospective study of patients with ischemic stroke discharged from 3 hospitals in Seville (Spain), during the periods: 1999-2001, 2014-2016 and 2019-2020.
Results: 1,379 patients were included, 42.6% women, mean age 69.1 (±11) years. HT was the most prevalent vascular risk factor in all periods, with a progressive increase in hypertensive patients (65.9% vs 69.6% vs 74%; P=.029). HT was especially frequent in patients≥80 years (73% vs 81.9% vs 85.2%; P=.029). At discharge, progressively more antihypertensive drugs were used (in 65% vs 85.1 vs 90.2% of patients; P=.0001), with a clear increase in the number of antihypertensive drugs used (mean 0.9±0.8 vs 1.5±1 vs 1.8±0.8 drugs, P=.0001). The use of diuretics (13.7%-39.3%-65.3%; p=0.0001), ACE inhibitors (35.5%-43.3%-53.4%; P=.0001) and angiotensin receptor blockers (12.2%-24%-32.4%; P=.0001) increased progressively. On the contrary, the use of calcium antagonists decreased (24%-19.9%-13.7%; P=.0001).
Conclusions: In the last 2 decades there has been a greater role for HT among patients with their first ischemic cerebrovascular event. Greater and better control of HT is necessary to reduce the enormous burden of cerebrovascular disease.
