Diuretics are preferred first-line over CCBs to optimize reduction of cardiovascular events .
The review does not distinguish between CCBs , ACE inhibitors or ARBs , but does provide evidence supporting the use of CCBs over beta-blockers .
BACKGROUND Calcium channel blockers ( CCBs ) are a relatively new antihypertensive class .
The effect of first-line CCBs on the prevention of cardiovascular events , as compared with other antihypertensive drug classes , is unknown .
OBJECTIVES To determine whether CCBs used as first-line therapy for hypertension are different from other first-line drug classes in reducing the incidence of major adverse cardiovascular events .
Cardiovascular outcomes in the African American Study of Kidney Disease and Hypertension (AASK) Trial.
BACKGROUND Patients with chronic kidney disease are at increased risk for cardiovascular ( CV ) events . METHODS We r and omly assigned 1,094 African Americans with hypertensive nephrosclerosis ( glomerular filtration rate [ GFR ] , 20 to 65 mL/min/1.73 m(2 ) [ 0.33 to 1.08 mL/s ] ) to initial antihypertensive treatment with either : ( 1 ) a beta-blocker , metoprolol ; ( 2 ) an angiotensin-converting enzyme inhibitor , ramipril ; or ( 3 ) a dihydropyridine calcium channel blocker , amlodipine , and either a usual-blood pressure ( BP ) or low-BP treatment goal . Using a design powered to detect renal outcome differences , we compared the effect of treatment on the CV event rate ( cardiac death , myocardial infa rct ion , stroke , and heart failure ) during a mean follow-up period of 4.1 years and determined baseline factors that predict CV outcomes . RESULTS Thirty-one patients died of CV disease ( 0.7%/patient-year ) , and 149 patients experienced at least 1 CV outcome ( 3.3%/patient-year ) . Overall , 202 CV events ( 4.5%/patient-year ) occurred . The CV outcome rate was not related significantly to r and omized interventions . In multivariable analyses , 7 baseline risk factors remained independently associated with increased risk for the CV composite outcome after controlling for age , sex , baseline GFR , and baseline proteinuria group : pulse pressure , duration of hypertension , abnormal electrocardiogram result , non-high-density lipoprotein cholesterol level , serum urea nitrogen level , urine protein-creatinine ratio , urine sodium-potassium ratio , and annual income less than 15,000 dollars . CONCLUSION Neither r and omized class of antihypertensive therapy nor BP level had a significant effect on the occurrence of CV events , possibly because of limited power . However , this analysis identifies unique and potentially modifiable CV risk factors in this high-risk cohort
