Abstract
Cardiovascular diseases (CVD) represent a significant health problem in all countries world-wide and in the developed world, including the Czech Republic, in particular. The underlying cause in the majority of CVD patients is atherosclerosis and its complications, respectively. The present paper focuses on prevention and timely treatment of atherosclerosis. Management should be comprehensive and should target the risk factors (RF). Hypertension, hyperlipoproteinaemia and dyslipidemia (HLP and DLP), type 2 diabetes mellitus (T2DM), visceral fat obesity and cigarette smoking are the dominating RFs. Even though all RFs have to be managed simultaneously and it is not possible to focus on just one of them, for the sake of clarity, this paper discusses hypertension and the use of telmisartan, a representative of one the most up-to-date group of antihypertensives. There is a growing evidence that it is not always just a reduction of a specific risk that is important but also the mode of treatment. For example, to reduce a CV risk in a patient with hypertension but also, for example, with metabolic syndrome, it is more beneficial to treat the patient with rennin-angiotensin system (RAS) blocking agents, possibly in a combination with calcium channels antagonists, than to use "traditional" (older) treatment approach with a combination of a beta/blocker and diuretic. Among the RAS-modifying agents, ACE inhibitors and sartans are the most widely used. Among sartans, telmisartan is very well-tolerated and has evidence from a large interventional study for its effect on reducing the CV risk.

Abstract
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.
