Predictors of cardiovascular events in patients with type 2 diabetic nephropathy and hypertension: a case for albuminuria.

Individuals with type 2 diabetes and nephropathy represent a particularly high-risk group for both adverse cardiac as well as renal events. Using the Irbesartan in Diabetic Nephropathy Trial (IDNT) cohort, our objective was to determine baseline characteristics of individuals with type 2 diabetic nephropathy and hypertension predictive for cardiac events. IDNT identified 1715 individuals with type 2 diabetic nephropathy and hypertension having serum creatinine of 1.0 to 3.0 mg/dL and urinary albumin excretion rates > or = 900 mg/day. A cardiovascular (CV) composite was used consisting of CV death, nonfatal MI, hospitalization for heart failure, stroke, amputation, and coronary and peripheral revascularization. Using multivariable Cox regression analysis, 41 baseline characteristics determined a priori were analyzed for their potential relationship to risk of experiencing a CV event. Of the 1715 individuals, 518 (30.2%) had at least one of the CV composite end points. Older age, male gender, longer duration of diabetes, history of cardiovascular disease, history of CHF, high urinary albumin:creatinine ratio, and low serum albumin were strong predictors for CV events; of these, prior history of CVD (RR 2.00, 95% CI 1.63-2.45; P < 0.0001) and high urinary albumin:creatinine ratio (RR 1.29 per natural log unit, 95% CI 1.13-1.48; P = 0.0002) at baseline were highly predictive for cardiovascular events. In conclusion, among individuals with hypertension and diabetic nephropathy, both the degree of albuminuria and lower serum albumin levels provide additional prognostic information concerning cardiovascular risk, in addition to traditional coronary risk factors.

Calcium antagonists in the treatment of hypertension in patients with ischaemic heart disease.

Are lives saved or heart attacks prevented by antihypertensive therapy, as a result of blood pressure reduction alone, or because of other properties of the antihypertensive medications which are independent of blood pressure lowering? Long-acting calcium antagonists seem to be as effective as thiazide diuretics and angiotensin-converting enzyme (ACE) inhibitors in preventing all-cause mortality and stroke in patients with hypertension, but are probably inferior to ACE inhibitors in preventing coronary artery disease. In patients with symptomatic coronary artery disease, calcium antagonists are generally as effective as beta-blockers in relieving angina and improving exercise time-to-onset of angina or ischaemia. Unstable angina or myocardial infarction require treatment with a beta-blocker, with an ACE inhibitor added when necessary for blood pressure control or if there is significant left ventricular (LV) dysfunction. If beta-blockers are contraindicated and if there is no LV dysfunction, a non-dihydropyridine calcium antagonist can be substituted.

Managing the hypertensive patient with ischemic heart disease.

Thiazide diuretics, b-blockers, calcium channel blockers, and angiotensin converting enzyme (ACE) inhibitors are all superior to placebo for the primary prevention of coronary events in patients with hypertension. Recent studies have shown that ACE inhibitors are better than other antihypertensive agents in lowering overall cardiovascular morbidity and mortality, especially stroke. Blood pressure should be aggressively lowered (to < 140/90 mm Hg), especially in diabetic patients (to < 130/80 mm Hg), but care should be exercised in lowering the diastolic blood pressure below 65 mm Hg in patients with significant occlusive coronary artery disease. Hypertension in patients with stable angina should be treated with a b-blocker (alternatively a calcium channel blocker) together with an ACE inhibitor. Patients with hypertension and acute coronary syndrome (unstable angina or myocardial infarction) should be treated with a b-blocker, and with an ACE inhibitor if there is left ventricular dysfunction. A thiazide diuretic and/or a dihydropyridine calcium channel blocker could be added for blood pressure control. Calcium channel blockers should be avoided if there is significant left ventricular dysfunction.

Current and emerging issues with B-type natriuretic peptide. Roundtable discussion.

A brief panel discussion was held on March 23, 2005, in New York City following a live symposium for primary care physicians discussing the roles of B-type natriuretic peptide in a variety of cardiovascular diseases. The participants were Dr. Marc A. Silver, Advocate Christ Medical Center, Oak Lawn, IL; Dr. Clive Rosendorff, Mount Sinai School of Medicine, New York, NY and VA Medical Center, Bronx, NY; Dr. Robert Berkowitz, Hackensack University Medical Center, Hackensack, NJ; and Dr. W. Franklin Peacock IV, The Cleveland Clinic Department of Emergency Medicine, Cleveland, OH. Dr. Silver moderated the discussion. The panel gathered to review some of the questions that emerged from the symposium and the questions raised by the attendees. These are of interest and importance to all interested in heart failure and B-type natriuretic peptide.
