First-line low-dose thiazides reduce all morbidity and mortality outcomes .
First-line ACE inhibitors and calcium channel blockers may be similarly effective but the evidence is less robust .
First-line high-dose thiazides and first-line beta-blockers are inferior to first-line low-dose thiazides
BACKGROUND Sustained elevated blood pressure , unresponsive to lifestyle measures , leads to a critically important clinical question : What class of drug to use first-line ?
This review answers that question .
OBJECTIVES PRIMARY OBJECTIVE To quantify the benefits and harms of the major first-line anti-hypertensive drug classes : thiazides , beta-blockers , calcium channel blockers , angiotensin converting enzyme ( ACE ) inhibitors , alpha-blockers , and angiotensin II receptor blockers ( ARB ) .
Trial of Secondary Prevention With Atenolol After Transient Ischemic Attack or Nondisabling Ischemic Stroke
Background and Purpose : & bgr;‐Blockers prevent vascular events in patients after myocardial infa rct ion and lower blood pressure , the main risk factor for stroke . Hence , we assessed the effects of atenolol on the occurrence of death from vascular causes , stroke , or myocardial infa rct ion and on blood pressure in patients after a transient ischemic attack or nondisabling ischemic stroke . Methods : In a double‐blind , placebo‐controlled r and omized clinical trial we studied the occurrence of the outcome event death from vascular causes , nonfatal stroke , or nonfatal myocardial infa rct ion and the outcome event fatal or nonfatal stroke as well as blood pressure on follow‐up . A total of 1,473 aspirin‐treated patients with transient ischemic attack or nondisabling ischemic stroke were r and omized to 50 mg atenolol daily or placebo . The mean follow‐up was 2.6 years . Results : Patients on atenolol had a risk of 97/732 ( 13.3 % ) for the combined outcome event versus a risk of 95/741 ( 12.8 % ) for those on placebo ( adjusted hazard ratio , 1.00 ; 95 % confidence interval , 0.76‐1.33 ) . The adjusted hazard ratio for fatal or nonfatal stroke was 0.82 ( 95 % confidence interval , 0.57‐1.19 ) . More patients on & bgr;‐blocker ( 153 ) reported adverse effects than on placebo ( 103 ) . At the first follow‐up visit after r and omization ( median at 4 months ) systolic blood pressure in the atenolol group had dropped by 8.0 mm Hg compared with 2.2 mm Hg in the placebo group ( difference , 5.8 mm Hg ; 95 % confidence interval , 2.9‐8.6 mm Hg ) . For diastolic blood pressure this difference was 2.9 mm Hg ( 95 % confidence interval , 1.5‐4.4 mm Hg ) . Conclusions : Our data neither confirm nor rule out that atenolol prevents important vascular events in patients after transient ischemic attack or nondisabling ischemic stroke , given the modest effect on blood pressure , the restrictions in patient selection , and the limited number of patient‐years .
