Antihypertensive drugs used to treat predominantly healthy adults aged 18 to 59 years with mild to moderate primary hypertension have a small absolute effect to reduce cardiovascular mortality and morbidity primarily due to reduction in cerebrovascular mortality and morbidity .
All-cause mortality and coronary heart disease were not reduced .
There is lack of good evidence on withdrawal due to adverse events .
BACKGROUND Hypertension is an important risk factor for adverse cardiovascular events including stroke , myocardial infa rct ion , heart failure and renal failure .
The main goal of treatment is to reduce these events .
Systematic review s have shown proven benefit of antihypertensive drug therapy in reducing cardiovascular morbidity and mortality but most of the evidence is in people 60 years of age and older .
We wanted to know what the effects of therapy are in people 18 to 59 years of age .
OBJECTIVES To quantify antihypertensive drug effects on all-cause mortality in adults aged 18 to 59 years with mild to moderate primary hypertension .
To quantify effects on cardiovascular mortality plus morbidity ( including cerebrovascular and coronary heart disease mortality plus morbidity ) , withdrawal due adverse events and estimate magnitude of systolic blood pressure ( SBP ) and diastolic blood pressure ( DBP ) lowering at one year .
The QUinapril Ischemic Event Trial (QUIET): evaluation of chronic ACE inhibitor therapy in patients with ischemic heart disease and preserved left ventricular function.
Angiotensin-converting enzyme inhibitors improve endothelial function , inhibit experimental atherogenesis , and decrease ischemic events . The Quinapril Ischemic Event Trial was design ed to test the hypothesis that quinapril 20 mg/day would reduce ischemic events ( the occurrence of cardiac death , resuscitated cardiac arrest , nonfatal myocardial infa rct ion , coronary artery bypass grafting , coronary angioplasty , or hospitalization for angina pectoris ) and the angiographic progression of coronary artery disease in patients without systolic left ventricular dysfunction . A total of 1,750 patients were r and omized to quinapril 20 mg/day or placebo  and followed a mean of 27 + /- 0.3 months . The 38 % incidence of ischemic events was similar for both groups ( RR 1.04 ; 95 % confidence interval 0.89 to 1.22 ; p = 0.6 ) . There was also no significant difference in the incidence of patients having angiographic progression of coronary disease ( p = 0.71 ) . The rate of development of new coronary lesions was also similar in both groups ( p = 0.35 ) . However , there was a difference in the incidence of angioplasty for new ( previously unintervened ) vessels ( p = 0.018 ) . Quinapril was well tolerated in patients after angioplasty with normal left ventricular function . Quinapril 20 mg did not significantly affect the overall frequency of clinical outcomes or the progression of coronary atherosclerosis . However , the absence of the demonstrable effect of quinapril may be due to several limitations in study design
