Randomized Controlled Trial
Single risk factors, such as hypertension and dyslipidemia, can combine to exacerbate the development and severity of cardiovascular disease. Treatment goals may be more effectively achieved if multiple disease factors are targeted with combination treatment. We enrolled 202 patients who were randomly divided into the following three groups: telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg, telmisartan 80 mg + rosuvastatin 20 mg, and telmisartan/amlodipine 80/5 mg. The primary efficacy variables were changes from baseline in mean sitting systolic blood pressure (MSSBP) between telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan 80 mg + rosuvastatin 20 mg at 8 weeks, and the percent changes from baseline in low-density lipoprotein (LDL) cholesterol between telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan/amlodipine 80/5 mg at 8 weeks. The secondary efficacy variables were changes in MSSBP, mean sitting diastolic blood pressure (MSDBP), LDL cholesterol and other lipid levels at 4 weeks and 8 weeks, as well as observed adverse events during follow-up. There were no significant differences between the three groups in demographic characteristics and no significant difference among the three groups in terms of baseline characteristics for the validity evaluation variables. The mean overall treatment compliance in the three groups was, respectively, 98.42%, 96.68%, and 98.12%, indicating strong compliance for all patients. The Least-Square (LS) mean (SE) for changes in MSSBP in the two (telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan 80 mg + rosuvastatin 20 mg) groups were -19.3 (2.68) mm Hg and -6.69 (2.76) mm Hg. The difference between the two groups was significant (-12.60 (2.77) mm Hg, 95% CI -18.06 to -7.14, P < .0001). The LS Mean for the percent changes from baseline in LDL cholesterol in the two (telmisartan/amlodipine 80/5 mg + rosuvastatin 20 mg and telmisartan/amlodipine 80/5 mg) groups were -52.45 (3.23) % and 2.68 (3.15) %. The difference between the two groups was significant (-55.13 (3.20) %, 95% CI -61.45 to -48.81, P < .0001). There were no adverse events leading to discontinuation or death. Combined administration of telmisartan/amlodipine 80/5 mg and rosuvastatin 20 mg for the treatment of hypertensive patients with dyslipidemia significantly reduces blood pressure and improves lipid control.

Journal of Veterinary Internal Medicine Jul 2021Use of telmisartan for the treatment of proteinuria in dogs has not been thoroughly investigated.
BACKGROUND
Use of telmisartan for the treatment of proteinuria in dogs has not been thoroughly investigated.
HYPOTHESIS/OBJECTIVES
Telmisartan can be effective for the treatment of proteinuria in dogs.
ANIMALS
Forty-four client-owned dogs with proteinuria.
METHODS
Retrospective study. Dogs diagnosed with clinically relevant proteinuria (nonazotemic dogs with a urine protein-to-creatinine ratio [UPC] ≥2 and azotemic dogs with UPC ≥0.5) were separated into 3 groups: telmisartan alone, with benazepril, or with mycophenolate. The UPC was recorded before treatment and at subsequent follow-ups (1, 3, 6, and 12 months, as available). Response to treatment was categorized as complete (UPC ˂0.5), partial (UPC decreased by ≥50% but still ≥0.5), or no response (UPC decreased by <50%). Serum creatinine and potassium concentrations and arterial pressure also were recorded.
RESULTS
In the telmisartan group, treatment response (UPC ˂0.5 or decreased by ≥50%) was observed in 70%, 68%, 80%, and 60% of dogs at 1, 3, 6, and 12 months follow-up, respectively. No significant changes were noted in serum creatinine or potassium concentrations, or in arterial blood pressure at all follow-up times. Adverse effects consisted of mild self-limiting gastrointestinal signs in 5 dogs. Two dogs developed clinically relevant azotemia that required discontinuation of the treatment before the first follow-up.
CONCLUSIONS AND CLINICAL IMPORTANCE
Telmisartan can be considered for treatment of proteinuria in dogs, alone or in combination with other treatments for proteinuria.

Review
Cardiovascular risk reduction has been the target of several large clinical trials in the last decade. As the activation of the renin-angiotensin-aldosterone system (RAAS) plays a central role in the pathogenesis of atherosclerosis and cardiovascular disease, RAAS blockade has been suggested to be among the most efficient cardioprotective interventions, as revealed with the angiotensin converting enzyme (ACE) inhibitors trials. The angiotensin receptor blockers' (ARBs) efficacy in lowering blood pressure has been very well established. Telmisartan is however the first ARB to show a promising role in reducing cardiovascular risk in high-risk patients. This article will highlight the role of telmisartan in cardioprotection, underlying specifically the results of two major randomized controlled trials: ONTARGET (ONgoing Telmisartan Alone and in combination with Ramipril Global Endpoint Trial) and TRANSCEND (Telmisartan Randomized AssessmeNt Study in aCE-iNtolerant subjects with cardiovascular Disease).

Comparative Study Randomized Controlled Trial
BACKGROUND
In patients who have vascular disease or high-risk diabetes without heart failure, angiotensin-converting-enzyme (ACE) inhibitors reduce mortality and morbidity from cardiovascular causes, but the role of angiotensin-receptor blockers (ARBs) in such patients is unknown. We compared the ACE inhibitor ramipril, the ARB telmisartan, and the combination of the two drugs in patients with vascular disease or high-risk diabetes.
METHODS
After a 3-week, single-blind run-in period, patients underwent double-blind randomization, with 8576 assigned to receive 10 mg of ramipril per day, 8542 assigned to receive 80 mg of telmisartan per day, and 8502 assigned to receive both drugs (combination therapy). The primary composite outcome was death from cardiovascular causes, myocardial infarction, stroke, or hospitalization for heart failure.
RESULTS
Mean blood pressure was lower in both the telmisartan group (a 0.9/0.6 mm Hg greater reduction) and the combination-therapy group (a 2.4/1.4 mm Hg greater reduction) than in the ramipril group. At a median follow-up of 56 months, the primary outcome had occurred in 1412 patients in the ramipril group (16.5%), as compared with 1423 patients in the telmisartan group (16.7%; relative risk, 1.01; 95% confidence interval [CI], 0.94 to 1.09). As compared with the ramipril group, the telmisartan group had lower rates of cough (1.1% vs. 4.2%, P<0.001) and angioedema (0.1% vs. 0.3%, P=0.01) and a higher rate of hypotensive symptoms (2.6% vs. 1.7%, P<0.001); the rate of syncope was the same in the two groups (0.2%). In the combination-therapy group, the primary outcome occurred in 1386 patients (16.3%; relative risk, 0.99; 95% CI, 0.92 to 1.07); as compared with the ramipril group, there was an increased risk of hypotensive symptoms (4.8% vs. 1.7%, P<0.001), syncope (0.3% vs. 0.2%, P=0.03), and renal dysfunction (13.5% vs. 10.2%, P<0.001).
CONCLUSIONS
Telmisartan was equivalent to ramipril in patients with vascular disease or high-risk diabetes and was associated with less angioedema. The combination of the two drugs was associated with more adverse events without an increase in benefit. (ClinicalTrials.gov number, NCT00153101 [ClinicalTrials.gov].).

Randomized Controlled Trial
BACKGROUND
Eggs are a rich source of essential nutrients, but they are also a source of dietary cholesterol. Therefore, some guidelines recommend limiting egg consumption. However, there is contradictory evidence on the impact of eggs on diseases, largely based on studies conducted in high-income countries.
OBJECTIVES
Our aim was to assess the association of egg consumption with blood lipids, cardiovascular disease (CVD), and mortality in large global studies involving populations from low-, middle-, and high-income countries.
METHODS
We studied 146,011 individuals from 21 countries in the Prospective Urban Rural Epidemiology (PURE) study. Egg consumption was recorded using country-specific validated FFQs. We also studied 31,544 patients with vascular disease in 2 multinational prospective studies: ONTARGET (Ongoing Telmisartan Alone and in Combination with Ramipril Global End Point Trial) and TRANSCEND (Telmisartan Randomized Assessment Study in ACEI Intolerant Subjects with Cardiovascular Disease). We calculated HRs using multivariable Cox frailty models with random intercepts to account for clustering by study center separately within each study.
RESULTS
In the PURE study, we recorded 14,700 composite events (8932 deaths and 8477 CVD events). In the PURE study, after excluding those with history of CVD, higher intake of egg (≥7 egg/wk compared with <1 egg/wk intake) was not significantly associated with blood lipids, composite outcome (HR: 0.96; 95% CI: 0.89, 1.04; P-trend = 0.74), total mortality (HR: 1.04; 95% CI: 0.94, 1.15; P-trend = 0.38), or major CVD (HR: 0.92; 95% CI: 0.83, 1.01; P-trend = 0.20). Similar results were observed in ONTARGET/TRANSCEND studies for composite outcome (HR 0.97; 95% CI: 0.76, 1.25; P-trend = 0.09), total mortality (HR: 0.88; 95% CI: 0.62, 1.24; P-trend = 0.55), and major CVD (HR: 0.97; 95% CI: 0.73, 1.29; P-trend = 0.12).
CONCLUSIONS
In 3 large international prospective studies including ∼177,000 individuals, 12,701 deaths, and 13,658 CVD events from 50 countries in 6 continents, we did not find significant associations between egg intake and blood lipids, mortality, or major CVD events. The ONTARGET and TRANSCEND trials were registered at clinicaltrials.gov as NCT00153101. The PURE trial was registered at clinicaltrials.gov as NCT03225586.

Cardiac injury is the main dose-limiting factor for doxorubicin (Dox) use as an anticancer agent. The cardiotoxicity of Dox is linked to a number of complex mechanisms, including oxidative stress, mitochondrial damage, intracellular calcium dysregulation, and apoptosis/necrosis. This study investigates several aspects of Dox-induced cardiotoxicity. We investigated the effects of pre-treatment with rosuvastatin and telmisartan, which were used in different doses alone or combination, on the acute cardiotoxicity induced by Dox. The results of this study showed that Dox induced significant pathological changes in the cardiomyocytes. Adverse effects were observed on several biomarkers related to cardiac damage like cardiac troponin I (cTnI) and lactate dehydrogenase (LDH), oxidative stress like malondialdehyde (MDA), an inflammatory process like interleukin-17 (IL-17) with important histopathological changes. We illusterate the cardio-protective contribution of the two pharmacological agents against the acute cardiotoxic effects of Dox. This is manifested by the significant improvement in the biomarker levels and the associated histological damage. This study points out the beneficial use of both rosuvastatin and telmisartan alone or in combination as a clinical option for decreasing the acute toxicity of Dox on cardiomyocytes.

Meta-Analysis Review
This study aimed to evaluate the efficacy of single-pill combination (SPC) antihypertensive drugs in patients with uncontrolled essential hypertension. Through Searching Pubmed, EMBASE, the Cochrane Library, and Web of Science collected only randomized controlled trials on the efficacy of single-pill combination antihypertensive drugs in people with uncontrolled essential hypertension. The search period is from the establishment of the database to July 2022. The methodological quality of the included studies was assessed using the Cochrane Risk of Bias Assessment, and statistical analyses were performed using Review Manage 5.3 and Stata 15.1 software. This review ultimately included 32 references involving 16 273 patients with uncontrolled essential hypertension. The results of the network meta-analysis showed that a total of 11 single-pill combination antihypertensive drugs were included, namely: Amlodipine/valsartan, Telmisartan/amlodipine, Losartan/HCTZ, Candesartan/HCTZ, Amlodipine/benazepril, Telmisartan/HCTZ, Valsartan/HCTZ, Irbesartan/amlodipine, Amlodipine/losartan, Irbesartan/HCTZ, and Perindopril/amlodipine. According to SUCRA, Irbesartan/amlodipine may rank first in reducing systolic blood pressure (SUCRA: 92.2%); Amlodipine/losartan may rank first in reducing diastolic blood pressure (SUCRA: 95.1%); Telmisartan/amlodipine may rank first in blood pressure control rates (SUCRA: 83.5%); Amlodipine/losartan probably ranks first in diastolic response rate (SUCRA: 84.5%). Based on Ranking Plot of the Network, we can conclude that single-pill combination antihypertensive drugs are superior to monotherapy, and ARB/CCB combination has better advantages than other SPC in terms of systolic blood pressure, diastolic blood pressure, blood pressure control rate, and diastolic response rate. However, due to the small number of some drug studies, the lack of relevant studies has led to not being included in this study, which may impact the results, and readers should interpret the results with caution.

Hypertension is a high-risk factor for developing coronary heart disease and stroke. Endothelial dysfunction and arterial remodeling can lead to increased vascular wall thickness and arterial stiffness. Previous studies showed that microRNA-483 (miR-483) enhances endothelial cell (EC) function. Here, we investigated the protective role of miR-483 in hypertension. Data collected from two patient cohorts showed that the serum miR-483-3p level was associated with the progression of hypertension and positively correlated with vascular function. In cultured ECs, miR-483 targets a number of endothelial dysfunction-related genes, such as transforming growth factor- (TGF-), connective tissue growth factor (CTGF), angiotensin-converting enzyme 1 (ACE1), and endothelin-1 (ET-1). Overexpression of miR-483-3p in ECs inhibited Ang II-induced endothelial dysfunction, revealed by the decreased expression of TGF-, CTGF, ACE1, and ET-1. Furthermore, miR-483-3p secreted from ECs was taken up by smooth muscle cells (SMCs) via the exosome pathway, which also decreased these genes in SMCs. Additionally, telmisartan could increase the aortic and serum levels of miR-483-3p in hypertension patients and spontaneous hypertension rats (SHR). These findings suggest that miR-483-3p exerts a protective effect on EC function during the onset of hypertension and thus may be considered a potential therapeutic target for hypertension-related cardiovascular diseases.

INTRODUCTION
African Americans (AAs) and European Americans (EAs) differ in Alzheimer's disease (AD) prevalence, risk factors, and symptomatic presentation and AAs are less likely to enroll in AD clinical trials.
METHODS
We conducted race-conscious pharmacoepidemiologic studies of 5.62 million older individuals (age ≥60) to investigate the association of telmisartan exposure and AD outcome using Cox analysis, Kaplan-Meier analysis, and log-rank test. We performed Mendelian randomization (MR) analysis of large ethnically diverse genetic data to test likely causal relationships between telmisartan's target and AD.
RESULTS
We identified that moderate/high telmisartan exposure was significantly associated with a reduced incidence of AD in the AAs compared to low/no telmisartan exposure (hazard ratio [HR] = 0.77, 95% CI: 0.65-0.91, p-value = 0.0022), but not in the non-Hispanic EAs (HR = 0.97, 95% CI: 0.89-1.05, p-value = 0.4110). Sensitivity and sex-/age-stratified patient subgroup analyses identified that telmisartan's medication possession ratio (MPR) and average hypertension daily dosage were significantly associated with a stronger reduction in the incidence of both AD and dementia in AAs. Using MR analysis from large genome-wide association studies (GWAS) (over 2 million individuals) across AD, hypertension, and diabetes, we further identified AA-specific beneficial effects of telmisartan for AD.
DISCUSSION
Randomized controlled trials with ethnically diverse patient cohorts are warranted to establish causality and therapeutic outcomes of telmisartan and AD.
HIGHLIGHTS
Telmisartan is associated with lower risk of Alzheimer's disease (AD) in African Americans (AAs). Telmisartan is the only angiotensin II receptor blockers having PPAR-γ agonistic properties with beneficial anti-diabetic and renal function effects, which mitigate AD risk in AAs. Mendelian randomization (MR) analysis demonstrates the specificity of telmisartan's protective mechanism to AAs.

Review
BACKGROUND
Pulmonary arterial hypertension (PAH) is one of several forms of pulmonary hypertension: a chronic disease of the pulmonary vasculature. The mean age at diagnosis is around 50 years old, with increasing prevalence in people over 70 years old (10% to 17%). The median survival to be approximately seven years with one-, three-, five-, and seven-year survival rates from time of diagnostic right-sided heart catheterization were 85%, 68%, 57%, and 49%, respectively. Several studies showed that calcium channel blockers (CCBs) reduce right ventricular hypertrophy and improve long-term haemodynamics in PAH.
OBJECTIVES
To evaluate the clinical efficacy and harms of CCBs for people with PAH.
SEARCH METHODS
The search strategy was provided by the Cochrane Airways Group Trials Search Co-ordinator. The following databases were searched from their inception until September 2014: the Cochrane Airways Group Register of Trials (CAGR); the Cochrane Central Register of Controlled Clinical Trials (CENTRAL) (The Cochrane Library,Issue 8 2014); MEDLINE (1948 to September 2014); EMBASE (1974 to September 2014); ClinicalTrials.gov; WHO trial portal; the Chinese Biomedical Databases (1979 to September 2014); CNKI: the Chinese Journals Full Text Database (1979 to September 2014), the Chinese Journals Full Text Database Century Journals (1979 to September 2014), the Chinese Doctoral Degree Thesis Full Text Database (1979 to September 2014), the Chinese Outstanding Master Degree Thesis Full Text Database (1979 to September 2014); VIP Database (1989 to September 2014) and WANFANG Database (1993 to September 2014). No language restriction was applied.
SELECTION CRITERIA
Fully published randomized controlled trials (RCTs) comparing CCBs with placebo or other treatment, or comparing CCBs as an adjunct to other treatments with other treatments alone, in patients with PAH.
DATA COLLECTION AND ANALYSIS
We used standard methods expected by Cochrane.
MAIN RESULTS
We found one RCT to include in this review but it was published only in abstract form with no data for evaluation.
AUTHORS' CONCLUSIONS
Currently, as there is lack of valid evidence, the efficacy and safety of CCBs is unproven in the treatment of PAH. However, the search strategy used for this review did identify four controlled clinical trials without randomization, three of which suggested treatment with CCBs may be beneficial in PAH. No adverse side effects of CCBs were reported. Confirmation of these findings by RCTs is recommended.
