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 .
Fasting glucose levels and incident diabetes mellitus in older nondiabetic adults randomized to receive 3 different classes of antihypertensive treatment: a report from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT).
BACKGROUND Elevated blood glucose levels are reported with thiazide-type diuretic treatment of hypertension . The significance of this finding is uncertain . Our objectives were to compare the effect of first-step antihypertensive drug therapy with thiazide-type diuretic , calcium-channel blocker , or angiotensin-converting enzyme inhibitor on fasting glucose ( FG ) levels and to determine cardiovascular and renal disease risks associated with elevated FG levels and incident diabetes mellitus ( DM ) in 3 treatment groups . METHODS We performed post hoc subgroup analyses from the Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial ( ALLHAT ) among nondiabetic participants who were r and omized to receive treatment with chlorthalidone ( n = 8419 ) , amlodipine ( n = 4958 ) , or lisinopril ( n = 5034 ) and observed for a mean of 4.9 years . RESULTS Mean FG levels increased during follow-up in all treatment groups . At year 2 , those r and omized to the chlorthalidone group had the greatest increase ( + 8.5 mg/dL [ 0.47 mmol/L ] vs + 5.5 mg/dL [ 0.31 mmol/L ] for amlodipine and + 3.5 mg/dL [ 0.19 mmol/L ] for lisinopril ) . The odds ratios for developing DM with lisinopril ( 0.55 [ 95 % confidence interval , 0.43 - 0.70 ] ) or amlodipine ( 0.73 [ 95 % confidence interval , 0.58 - 0.91 ] ) vs chlorthalidone at 2 years were significantly lower than 1.0 ( P<.01 ) . There was no significant association of FG level change at 2 years with subsequent coronary heart disease , stroke , cardiovascular disease , total mortality , or end-stage renal disease . There was no significant association of incident DM at 2 years with clinical outcomes , except for coronary heart disease ( risk ratio , 1.64 ; P = .006 ) , but the risk ratio was lower and nonsignificant in the chlorthalidone group ( risk ratio , 1.46 ; P = .14 ) . CONCLUSIONS Fasting glucose levels increase in older adults with hypertension regardless of treatment type . For those taking chlorthalidone vs other medications , the risk of developing FG levels higher than 125 mg/dL ( 6.9 mmol/L ) is modestly greater , but there is no conclusive or consistent evidence that this diuretic-associated increase in DM risk increases the risk of clinical events
