We found predominantly moderate quality evidence that all-cause mortality is similar when first-line RAS inhibitors are compared to other first-line antihypertensive agents .
First-line thiazides caused less HF and stroke than first-line RAS inhibitors .
Compared with first-line CCBs , first-line RAS inhibitors reduced HF but increased stroke .
The magnitude of the reduction in HF exceeded the increase in stroke .
The small differences in effect on blood pressure between the different classes of drugs did not correlate with the differences in the primary outcomes
BACKGROUND Renin-angiotensin system ( RAS ) inhibitors are widely prescribed for treatment of hypertension , especially for diabetic patients on the basis of postulated advantages for the reduction of diabetic nephropathy and cardiovascular morbidity and mortality .
Despite widespread use of angiotensin converting enzyme ( ACE ) inhibitors and angiotensin receptor blockers ( ARBs ) for hypertension in both diabetic and non-diabetic patients , the efficacy and safety of RAS inhibitors compared to other antihypertensive drug classes remains unclear .
OBJECTIVES To evaluate the benefits and harms of first-line RAS inhibitors compared to other first-line antihypertensive drugs in patients with hypertension .
Clinical Events in High-Risk Hypertensive Patients Randomly Assigned to Calcium Channel Blocker Versus Angiotensin-Converting Enzyme Inhibitor in the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial
The Antihypertensive and Lipid-Lowering treatment to prevent Heart Attack Trial ( ALLHAT ) provides a unique opportunity to compare the long-term relative safety and efficacy of angiotensin-converting enzyme inhibitor and calcium channel blocker – initiated therapy in older hypertensive individuals . Patients were r and omized to amlodipine ( n=9048 ) or lisinopril ( n=9054 ) . The primary outcome was combined fatal coronary heart disease or nonfatal myocardial infa rct ion , analyzed by intention-to-treat . Secondary outcomes included all-cause mortality , stroke , combined cardiovascular disease ( CVD ) , end-stage renal disease ( ESRD ) , cancer , and gastrointestinal bleeding . Mean follow-up was 4.9 years .  Blood pressure control was similar in nonblacks , but not in blacks . No significant differences were found between treatment groups for the primary outcome , all-cause mortality , ESRD , or cancer . Stroke rates were higher on lisinopril in blacks ( RR=1.51 , 95 % CI 1.22 to 1.86 ) but not in nonblacks ( RR=1.07 , 95 % CI 0.89 to 1.28 ) , and in women ( RR=1.45 , 95 % CI 1.17 to 1.79 ) , but not in men ( RR=1.10 , 95 % CI 0.92 to 1.31 ) . Rates of combined CVD were higher ( RR=1.06 , 95 % CI 1.00 to 1.12 ) because of higher rates for strokes , peripheral arterial disease , and angina , which were partly offset by lower rates for heart failure ( RR=0.87 , 95 % CI 0.78 to 0.96 ) on lisinopril compared with amlodipine .  Gastrointestinal bleeds and angioedema were higher on lisinopril . Patients with and without baseline coronary heart disease showed similar outcome patterns . We conclude that in hypertensive patients , the risks for coronary events are similar , but for stroke , combined CVD , gastrointestinal bleeding , and angioedema are higher and for heart failure are lower for lisinopril-based compared with amlodipine-based therapy . Some , but not all , of these differences may be explained by less effective blood pressure control in the lisinopril arm
