Abstract
Blood pressure lowering by all classes of antihypertensive drugs is accompanied by significant reductions of stroke and major cardiovascular (CV) events. Drugs acting on the renin-angiotensin-aldosterone system, such as angiotensin converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs), showed similar benefit on major CV events to other antihypertensive medications. In real-world practice, ARBs reduced by 10% the incidence of CV mortality, non-fatal myocardial infarction, non-fatal stroke and provided superior protection against CV events than ACEIs in high-risk patients. Despite similar antihypertensive properties and a favourable safety profile for both ACEIs and ARBs, evidence indicates that patients treated with ARBs have lower rates of withdrawal for adverse events and greater persistence to therapy than those treated with ACEIs. Among ARBs, olmesartan is one of the latest generation compounds introduced in clinical practice for treating hypertension: head-to-head comparative trials suggest that the efficacy of olmesartan is superior to that of commonly prescribed ACEIs (ramipril and perindopril). The drug, administered as a monotherapy or in combination with a dihydropyridine calcium channel blocker or a thiazide diuretic, has proved to be effective in maintaining blood pressure stability over 24 h, with a favourable safety profile and low discontinuation rates. These properties are pivotal for considering olmesartan as a useful antihypertensive agent especially for high-risk patients (e.g. elderly, diabetics, patients with metabolic syndrome).Funding: Article preparation and open access fee were funded by Menarini International Operations Luxembourg S.A.

Abstract
BACKGROUND Although the pathophysiological mechanisms of arterial hypertension are different in obese and lean patients, hypertension guidelines do not include specific recommendations for obesity-related hypertension and, therefore, there is a considerable uncertainty on which antihypertensive drugs should be used in this condition. Moreover, studies performed in general population suggested that some antihypertensive drugs may increase body weight, glycemia and LDL-cholesterol but it is unclear how this impact on drug choice in clinical practice in the treatment of obese hypertensive patients. Therefore, in order to identify current preferences of practitioners for obesity-related hypertension, in the present work we evaluated antihypertensive drug therapy in a cohort of 129 pharmacologically treated obese hypertensive patients (46 males and 83 females, aged 51.95 ± 10.1 years) that came to our observation for a nutritional consultation. METHODS Study design was retrospective observational. Differences in the prevalence of use of the different antihypertensive drug classes among groups were evaluated with χ(2) square analysis. Threshold for statistical significance was set at p < 0.05. RESULTS 41.1 % of the study sample was treated with one, 36.4 % with two and the remaining 22.5 % with three or more antihypertensive drugs. In patients under single drug therapy, β-blockers, ACEIs and ARBs accounted each for about 25 % of prescriptions. The prevalence of use of β-blockers was about sixfold higher in females than males. Diuretics were virtually never used in monotherapy regimens but were used in more than 60 % of patients on dual antihypertensive therapy and in all patients assuming three or more drugs. There was no significant difference in the prevalence of use of any of the aforementioned drugs among patients with obesity of type I, II and III or between patients with or without metabolic syndrome. CONCLUSIONS Our data show that no first choice protocol seems to be adopted in clinical practice for the treatment of obesity-related hypertension. Importantly, physicians do not seem to differentiate drug use according to the severity of obesity or to the presence of metabolic syndrome or to avoid drugs known to detrimentally affect body weight and metabolic profile in general population.

Abstract
BACKGROUND Metabolic syndrome (MetS) has been reported as a risk factor for cardiovascular events. The aim of the present study is to investigate the association between chronic angiotensin-converting enzyme inhibitors (ACE-I) therapy and the rate of periprocedural myocardial infarction (PMI) after elective coronary stenting among patients with MetS. METHODS The inclusion criteria were MetS and plan for elective percutaneous coronary intervention. To assess the effect of ACE-I treatment on the incidence of PMI, measurements of cardiac biomarkers (CK-MB mass and troponin I) were performed at baseline and 24 h after the procedure. RESULTS A total of 459 patients fulfilling the inclusion criteria were recruited to chronic ACE-I treatment and ACE-I naive groups in a 2/1 ratio. Baseline troponin I and CK-MB levels were similar in both treatment groups, whereas they were significantly lower in ACE-I group 24 h after the procedure. Univariate analysis identified body mass index (BMI), LDL cholesterol, nitrate and ACE-I use as significant factors for the development of PMI. Multivariate regression model revealed that body mass index increased and use of nitrate and ACE-I decreased the probability of PMI independent from confounding factors (OR 1.14, 95% CI 1.05-1.23, p = 0.002 for BMI; OR 0.26, 95% CI 0.14-0.48, p = 0.01 for nitrate use, OR 0.51, 95% CI 0.27-0.93, p = 0.03 for ACE-I use). CONCLUSIONS This prospective observational cohort trial demonstrated that chronic ACE-I therapy was an independent predictor for reduced PMI among patients with MetS who underwent elective coronary intervention.

Biomedical papers of the Medical Faculty of the University Palacky, Olomouc, Czechoslovakia. 2014;(3):412-21
Abstract
AIMS: The primary questions asked by the MEDINA (MEtabolic parameters, DIabetes mellitus and NephropAthy) study are: 1) Do angiotensin converting enzyme inhibitors (ACE-I) have any advantages over angiotensin receptor blockers (ARB)? 2) Should the other drug for combination be a diuretic or a calcium-channel blocker (CCB)? 3) How are the risks reduced by the co administration of a statin? METHODS A total of 439 hypertensive patients with metabolic syndrome and/or diabetes mellitus were randomized to 2 groups: group 1--ramipril (ACE-I) or perindopril and group 2--losartan (ARB). Hydrochlorothiazide (diuretic) or amlodipine (CCB) were added to both groups. As a third step, a statin was added. RESULTS Blood pressure decreased 24.1/13.3 mmHg in the ACE inhibitor group and 25.9/13.5 in the losartan group. The difference was insignificant. Adding either hydrochlorothiazide or amlodipin was equally effective. There were no significant differences on metabolic parameters in the trial arms. Cholesterol level decreased by 0.95 mmol/L in the ACE-I group and 1.02 mmol/L in the ARB group (ns). CONCLUSION MEDINA has so far confirmed the equivalence of ACE-I and ARB in hypertension treatment. Adding either diuretic or CCB was equally effective. Our data support the current recommendations on adding a statin to reduce cardiovascular risk.

Abstract
To evaluate the relationship between plasma plasminogen activator inhibitor-1 (PAI-1) and angiotensin II (Ang II) changes during treatment with imidapril and candesartan in hypertensive patients with metabolic syndrome. A total of 84 hypertensive patients with metabolic syndrome were randomized to imidapril 10 mg or candesartan 16 mg for 16 weeks. At weeks 4 and 8, there was a dose titration to imidapril 20 mg and candesartan 32 mg in nonresponders (systolic blood pressure (SBP) >140 and/or diastolic blood pressure (DBP) >90 mm Hg). We evaluated, at baseline and after 2, 4, 8, 12 and 16 weeks, clinic blood pressure, Ang II and PAI-1 antigen. Both imidapril and candesartan induced a similar SBP/DBP reduction (-19.4/16.8 and -19.5/16.3 mm Hg, respectively, P<0.001 vs. baseline). Both drugs decreased PAI-1 antigen after 4 weeks of treatment, but only the PAI-1 lowering effect of imidapril was sustained throughout the 16 weeks (-9.3 ng ml(-1), P<0.01 vs. baseline), whereas candesartan increased PAI-1 (+6.5 ng ml(-1), P<0.05 vs. baseline and P<0.01 vs. imidapril). Imidapril significantly decreased Ang II levels (-14.6 pg ml(-1) at week 16, P<0.05 vs. baseline), whereas candesartan increased them (+24.2 pg ml(-1), P<0.01 vs. baseline and vs. imidapril). In both groups there was a positive correlation between Ang II and PAI-1 changes (r=0.61, P<0.001 at week 16 for imidapril, and r=0.37, P<0.005 at week 16 for candesartan). Imidapril reduced plasma PAI-1 and Ang II levels, whereas candesartan increased them. This suggests that the different effect of angiotensin-converting enzyme inhibitors and Ang II blockers on Ang II production has a role in their different influence on fibrinolysis.

[Comprehensive management of cardiovascular risk. Focusing on telmisartan].
Ceska, R, Krutská, S, Zlatohlávek, L, Vrablík, M
Vnitrni lekarstvi. 2010;(8):839-44
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.

[Acute coronary syndrome with ST segment depression on ECG: novel outlook of an old problem].
Latfullin, IA, Kim, ZF
Kardiologiia. 2010;(1):51-61
Abstract
The lecture is devoted to morphological manifestations, clinical and prognostic features of acute coronary syndrome (ACS) with ST segment depressions on ECG. We have studied peculiarities of clinical course of this variant of ACS and its outcomes in 501 patients and suggested a scheme for stratification of patients in groups of risk of complicated course of ischemic heart disease. We have also studied 85 patients with ACS with ST segment depressions on ECG during anginal attack. In therapy of these patients we included drugs with potential metabolic action: trimetazidine (n=29), infusions of polarizing mixture (n=16), enalapril maleate (n=28), potassium succinate (n=12). It has been established that the application of trimetazidine improves course and prognosis of the disease.

Management of patients with nephrotic syndrome.
de Seigneux, S, Martin, PY
Swiss medical weekly. 2009;(29-30):416-22
Abstract
Nephrotic syndrome is characterised by proteinuria >3.5 g/24h, oedema, hypoalbuminaemia and hyperlipidaemia. Several glomerular diseases, either primary or secondary, may lead to nephrotic syndrome. Investigations for nephrotic syndrome include immunological and infectious evaluations. Renal biopsy is often mandatory, except in diabetes. Depending on aetiology specific treatment, often with immunosuppressive agents, may be implemented. In any cases nonspecific treatment should be started with ACE inhibitors or ARBs. Urinary protein loss leads to several complications: water and sodium retention, hyperlipidaemia, increased risk of thromboembolism and infection, anaemia and alteration of mineral metabolism. Each of these complications must be identified.

Abstract
The Antihypertensive and Lipid-Lowering Treatment to Prevent Heart Attack Trial (ALLHAT) is reevaluated considering information from new clinical trials, meta-analyses, and recent subgroup and explanatory analyses from ALLHAT, especially those regarding heart failure (HF) and the association of drug treatment with new-onset diabetes mellitus (DM) and its cardiovascular disease (CVD) consequences. Chlorthalidone was superior to (1) doxazosin mesylate in preventing combined CVD (CCVD) (risk ratio [RR], 1.20; 95% confidence interval [CI], 1.13-1.27), especially HF (RR, 1.80; 95% CI, 1.40-2.22) and stroke (RR, 1.26; 95% CI, 1.10-1.46); (2) lisinopril in preventing CCVD (RR, 1.10; 95% CI, 1.05-1.16), including stroke (in black persons only) and HF (RR, 1.20; 95% CI, 1.09-1.34); and (3) amlodipine besylate in preventing HF, overall (by 28%) and in hospitalized or fatal cases (by 26%). Central independent blinded reassessment of HF hospitalizations confirmed each comparison. Results were consistent by age, sex, race (except for stroke and CCVD), DM status, metabolic syndrome status, and renal function level. Neither amlodipine nor lisinopril was superior to chlorthalidone in preventing end-stage renal disease overall, by DM status, or by renal function level. In the chlorthalidone arm, new-onset DM was not significantly associated with CCVD (RR, 0.96; 95% CI, 0.88-2.42). Evidence from subsequent analyses of ALLHAT and other clinical outcome trials confirm that neither alpha-blockers, angiotensin-converting enzyme inhibitors, nor calcium channel blockers surpass thiazide-type diuretics (at appropriate dosage) as initial therapy for reduction of cardiovascular or renal risk. Thiazides are superior in preventing HF, and new-onset DM associated with thiazides does not increase CVD outcomes.
