Treatment of hypertension in individuals with the cardiometabolic syndrome: role of an angiotensin II receptor blocker, telmisartan.Francischetti EA, Celoria BM, Francischetti A, Genelhu VA Hypertension Clinic, Laboratory of Clinical and Experimental Pathophysiology (CLINEX), School of Medicine, Rio de Janeiro State University, Brazil. francischetti@globo.com Arterial hypertension is a global public health problem owing to its high prevalence and association with increased risk for cerebral, cardiac and renal events. Hypertension frequently clusters with other cardiometabolic risk factors, such as dysglycemia, low levels of high-density lipoprotein cholesterol and high triglyceride levels. These, along with other factors such as central obesity, increased inflammation, endothelial dysfunction and thrombosis, are components of the metabolic syndrome. All guidelines recommend that the first-line therapy in metabolic syndrome should be based on lifestyle modification, consisting of diet and moderate exercise for at least 30 min/day. Concerning drug treatment of hypertension associated with other cardiometabolic risk factors, many results of head-to-head studies have demonstrated a reduction in new-onset Type 2 diabetes in hypertensive patients treated with angiotensin-converting enzyme inhibitors and angiotensin receptor blockers, when compared with conventional antihypertensive therapy. The explanations of the different actions of both these drugs include several mechanisms related to pancreatic insulin release and insulin sensitivity improvement. Another mechanism by which the inhibition of the renin-angiotensin system may improve insulin sensitivity is through the partial peroxisome proliferator-activated receptor-gamma agonism of telmisartan. For that reason, telmisartan has been considered by some experts to be an antihypertensive agent that is particularly useful in the treatment of hypertension associated with cardiometabolic risk factors. The impact of the promising metabolic action exhibited by telmisartan on the outcome of hypertensive patients aggregating other cardiometabolic risk factors waits for adequately randomized and powered clinical trials.
