Abstract
AIMS: This meta-analysis aims to analyze the association of calcium channel blocker (CCB) use with COVID-19 clinical outcomes. METHODS PubMed, ProQuest, Science Direct, Scopus, and medRxiv databases were searched systematically in a limited period. The primary outcome was mortality. RESULTS A total of 119,298 patients from 31 eligible studies were included. Pooled analysis of the random-effect model revealed CCB was not associated with reduced mortality (OR = 1.21 [95%CI: 0.98-1.49], p = 0.08). Interestingly, subgroup analysis in hypertensive patients revealed significantly reduced mortality (OR = 0.69 [95%CI: 0.52-0.91], p = 0.009). CONCLUSION CCB usage was not associated with the outcome of COVID-19. However, CCB was associated with a decreased mortality rate in hypertensive COVID-19 patients.

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
Circulating NEFAs (non-esterified fatty acids) from adipose tissue lipolysis lead to endothelial dysfunction and insulin resistance in patients with the metabolic syndrome or Type 2 diabetes mellitus. The aim of the present study was to test the hypothesis that DHP (dihydropyridine) CCBs (calcium channel blockers) prevent NEFA-induced endothelial and haemorheological dysfunction independently of their antihypertensive properties. Using a double-blind cross-over study design, nifedipine, amlodipine, diltiazem or placebo were administered to eight healthy subjects for 2 days before each study day. On the study days, the following were assessed before and after the infusion of lipid and heparin to raise serum NEFAs: endothelial function, by measuring FBF (forearm blood flow) responses to ACh (acetylcholine); leucocyte activation, by ex vivo measurement of plasma MPO (myeloperoxidase) levels, adherent leucocyte numbers and whole blood transit time through microchannels; and oxidative stress, by determining plasma levels of d-ROMs (derivatives of reactive oxygen metabolites). Effects of the CCBs on NF-κB (nuclear factor κB) p65 phospholylation stimulated by NEFAs were assessed in cultured monocytic cells in vitro. Elevated NEFAs reduced the responses to ACh and significantly increased whole blood transit time, adherent leucocyte numbers and d-ROMs. Nifedipine and amlodipine, but not diltiazem, prevented NEFA-induced endothelial dysfunction, leucocyte activation and enhancement of oxidative stress without affecting BP (blood pressure), whereas all these drugs prevented NEFA-induced p65 activation in vitro. These results suggest that DHP CCBs, independent of their antihypertensive properties in humans, prevent NEFA-induced endothelial and haemorheological dysfunction through inhibition of NEFA-induced leucocyte activation, although the sensitivity to drugs of leucocyte Ca2+ channels may differ among cells.

Abstract
Fixed-dose combination (FDC) therapy with telmisartan 40 mg+amlodipine 5 mg (T40/A5) is expected to achieve tight blood pressure (BP) control because of the strong efficacy and long half-life of each drug. The aims of this study were to evaluate the 24-h antihypertensive efficacy of T40/A5 FDC therapy and to explore differences that may arise owing to different administration times in Japanese patients whose hypertension was not controlled by 5 mg of amlodipine per day. In this randomized clinical trial, 44 patients who had been taking amlodipine 5 mg per day and did not achieve their optimal BP target were enrolled (mean age: 67.8±10.2 years). The subjects were then randomly assigned to a T40/A5 morning or evening administration group (22 patients per group). At baseline and 8 weeks after randomization, we evaluated clinical BP and various laboratory values and performed ambulatory BP monitoring (ABPM). Clinical and mean BP evaluated with ABPM at 8 weeks (24 h, daytime, nighttime and early morning) were significantly decreased compared with BP at baseline. There were no significant differences in the diurnal BP profile change from baseline to 8 weeks between subjects in the morning and evening administration groups. There were also no significant differences in the diurnal BP profile change from baseline to 8 weeks between subjects with or without metabolic syndrome. We conclude that T40/A5 FDC therapy significantly decreased the 24-h mean and clinical BP, independent of administration time, in patients whose hypertension was not controlled by 5 mg of amlodipine.

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.

[The combination of an ACE inhibitor and a calcium channel blocker is an optimal combination for the treatment of hypertension].
Widimský, J
Vnitrni lekarstvi. 2009;(2):123-30
Abstract
Combination of drugs from different classes of antihypertensives provides an additional antihypertensive effect thus minimising the probability of adverse effects related to the dose of antihypertensive. Combination therapy is indicated for the following groups of hypertensive patients: (a) all hypertensive patients whose systolic blood pressure exceeds the target systolic blood pressure value by > 20 mm Hg, or whose diastolic blood pressure exceeds the target diastolic blood pressure value by > 10 mm Hg; (b) in patients with diabetes mellitus (because the target values are < 130/80 mm Hg); (c) patients with target organ damage; (d) patients with a kidney or cardiovascular disease (patients with IHD, patients after a cerebrovascular accident); (e) patients with overall cardiovascular risk according the SCORE > or = 5%. The advantage of fixed combinations resides in the fact that they increase compliance with treatment by reducing the number of pills taken by the patients. A fixed combination of the ACE inhibitor perindopril and the calcium channel blocker amlodipine proves optimal as has been shown by the results of the ASCOT-BPLA study. The launch of the above combination on this market should therefore be welcome. The fixed combination of perindopril and amlodipine will be indicated for hypertensive patients with uncontrolled hypertension or cardiovascular risk factors. This fixed combination will also be ideal for patients with a higher risk of diabetes mellitus, i.e. patients with a higher fasting glycaemia, in patients with impaired glucose tolerance and in patients with the metabolic syndrome. We strongly believe that it will improve the control of hypertension in our hypertensive patients, and improve the cardioprotective and nephroprotective effect of hypertension therapy.

Terapevticheskii arkhiv. 2008;(11):57-61
Abstract
AIM: To study effects of calcium antagonist amlodipine (normodipine) on blood pressure, heart rate variability (HRV) and carbohydrate metabolism in patients with metabolic syndrome (MS). MATERIAL AND METHODS The trial included 52 patients (37 females, 15 males) with MS. The examination at baseline and after 12 weeks of amlodipine treatment included: office blood pressure (BP) measurement, 24-h BP monitoring, exercise tolerance test, estimation of HRV and carbohydrate profile. Amlodipine was administered as monotherapy for 12 weeks. RESULTS A 12-week treatment with amlodipine demonstrated high antihypertensive effect (BP normalized in 72.7% patients) without negative effects on HRV and carbohydrate profile. CONCLUSION Monotherapy with calcium antagonist amlodipine (normodipine) has high antihypertensive efficacy and is metabolically neutral in MS patients.

Abstract
The aim of the study was to obtain a comparative evaluation of antihypertensive efficacy, tolerability and influence of combine therapy on myocardium mass, diastolic function of a left ventricle, lipid and carbohydrate exchange in patients with arterial hypertension in metabolic syndrome. Out of 40 examined cases 20 patients took enalapril and long-acting nifedipin and 20 ones--enalapril and moxonidine. All examination were been performed before administration of drugs and 6 months after the therapy. The dynamics of indices of ambulatory blood pressure monitoring, echocardiography, cycle ergometry, anthropometry, lipid, carbohydrate exchange and tolerability of conducted therapy was been evaluated. The use of this combination of the drugs may be recommended to be included in the treatment of arterial hypertension within the bounds of metabolic syndrome, as in most of cases they promote an achievement of target blood pressure level, have a cardioprotective action, high tolerability and favorable metabolic profile. The combination of enalapril and long-acting nifedipin has a more evident antihypertensive activity but a therapy with enalapril and moxonidine has a positive effect on the indices of carbohydrate exchange.
