Observational Study
OBJECTIVES
This analysis compared adherence, cardiovascular (CV) events and all-cause mortality incidence, and healthcare costs among hypertensive patients treated with perindopril (PER)/indapamide (IND)/amlodipine (AML) in single-pill combination (SPC) vs. multiple-pill combination, in a real-world setting in Italy.
METHODS
In this observational retrospective analysis of Italian administrative databases, adult patients treated with PER/IND/AML between 2010 and 2020 were divided into two cohorts: single-pill vs. multiple-pill. Patient data were available for at least one year before and after index date. Propensity score matching (PSM) was applied to reduce selection bias. Adherence was defined as proportion of days covered: non-adherence, <40%; partial adherence, 40-79%, and adherence ≥80%. Mortality incidence and CV events as single, or composite, endpoints were evaluated after first year of follow-up. Healthcare cost analyses were performed from the perspective of the Italian National Health Service.
RESULTS
Following PSM, the single-pill cohort included 12 150 patients, and the multiple-pill cohort, 6105. The SPC cohort had a significantly higher percentage of adherent patients vs. the multiple-pill cohort (59.9% vs. 26.9%, P < 0.001). Following the first year of follow-up, incidence of all-cause mortality, and combined endpoint of all-cause mortality and CV events were lower in the SPC cohort compared with multiple-pill cohort. Average annual direct healthcare costs were lower in the single-pill cohort (€2970) vs. multiple-pill cohort (€3642); cost of all drugs and all-cause hospitalizations were major contributors.
CONCLUSION
The SPC of PER/IND/AML, compared with multiple-pill combination, is associated with higher adherence to medication, lower incidence of CV events and mortality, and reduced healthcare costs.

ABSTRACT
Most cases of primary microvascular angina pectoris (PMVA) are diagnosed clinically, but the etiology and pathological mechanisms are unknown. The effect of routine clinical medications is minimal, and PMVA can progress to serious cardiovascular events. To improve the diagnosis and effective treatment of this disease, this study was designed to diagnose PMVA via cardiovascular magnetic resonance (CMR) and the coronary angiography thrombolysis in myocardial infarction (TIMI) blood flow grade, as well as to analyze vascular endothelial function to elucidate the pathogenesis of PMVA and compare the effects of routine clinical medications.The present randomized controlled trial including a parallel control group will be conducted on 63 PMVA patients in our cardiovascular department. The patients will be selected and randomly divided into the control, diltiazem, and nicorandil groups. The control group will be administered routine drug treatments (aspirin, atorvastatin, betaloc ZOK, perindopril, and isosorbidemononitrate sustained-release tablets). The diltiazem group will be additionally treated with 90 mg qd diltiazem sustained-release capsules. The nicorandil group was additionally given 5 mg tid nicorandil tablets. Coronary angiography will be performed before treatment, the severity and frequency of chest pain will be evaluated before and after 9 months of treatment, and homocysteine and von Willebrand factor levels will be measured. Electrocardiography, echocardiography, dynamic electrocardiography, a treadmill exercise test, and CMR will be performed. Sex, age, body mass index, complications, smoking, and family history will also be recorded. The SPSS19.0 statistical software package will be used to analyze the data. The measurements will be expressed as the mean ± standard deviation. Measurement data will be compared between the groups using Student's t-test. A relative number description will be used for the counting data, and the chi-squaretest will be used to compare the groups. A multivariate logistic regression analysis will be performed A P-value < .05 will be considered significant.The direct indices (CMR and coronary angiographic TIMI blood flow grade) may improve after adding diltiazem or nicorandil during routine drug treatments (such as aspirin, statins, and nitrates) in PMVA patients, and indirect indices (homocysteine and von Willebrand factor levels) may be reduced.

Observational Study
INTRODUCTION
Most patients with hypertension in sub-Saharan Africa require two or more drugs to control their blood pressure. Triple fixed-dose combination therapy of perindopril arginine/indapamide/amlodipine is more effective in lowering blood pressure, offers better target organ protection and has increased adherence compared to monotherapy and free combination therapy, and is safe to use. This observational study evaluates the effectiveness of perindopril arginine/indapamide/amlodipine in controlling blood pressure at least 1 month after treatment initiation and assesses patient- and physician- reported drug tolerance over a 3-month period in Madagascar and Mauritius.
METHODS
A total of 198 patients with hypertension in ambulatory care who had been on fixed-dose combination of perindopril arginine, indapamide, and amlodipine for at least 4 weeks were included. The main outcome measures were changes in systolic and diastolic blood pressure, attainment of blood pressure control under 140/90 mmHg and 130/80 mmHg, self-reported drug tolerance by the patient, and perceived drug tolerance by the treating physician. Data was collected at 1 month and 3 months.
RESULTS
Mean systolic blood pressure was significantly lower at the 1-month (- 3.4 mmHg, p = 0.002) and 3-month (- 8.5 mmHg, p < 0.0001) visits. Diastolic blood pressure also decreased significantly (- 2.4 mmHg at 1-month, p = 0.017 and - 5.4 mmHg at the 3-month visits, p < 0.0001). At 3 months, 80.4% of the patients attained blood pressure targets less than 140/90 mmHg and 42.7% attained targets less than 130/80 mmHg on the basis of their baseline blood pressure. Excellent drug tolerance was reported by more than 90% of patients and physicians at the 1-month visit and by more than 95% at the 3-month visit.
CONCLUSION
Triple fixed-dose therapy of perindopril arginine/indapamide/amlodipine continues to show additional blood pressure-lowering capacity even months after initiating the treatment in patients with hypertension in Madagascar and Mauritius. It is also well tolerated by patients with hypertension and assessed as safe to use by physicians.

Review
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. (M.I.O.L.).

BACKGROUND
Luhong formula (LHF)-a traditional Chinese medicine containing Cervus nippon Temminck, Carthamus tinctorius L., Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, Codonopsis pilosula (Franch.) Nannf., Cinnamomum cassia Presl, and Lepidium apetalum Willd-is used in the treatment of heart failure, but little is known about its mechanism of action. We have investigated the effects of LHF on antifibrosis.
METHODS
Forty-eight SD male rats were randomly assigned into six groups ( = 8), model group, sham-operation group, perindopril group (0.036 mg/ml), LHF high doses (LHF-H, 1.44 g/mL), LHF middle doses (LHF-M, 0.72 g/mL), and LHF low doses (LHF-L, 0.36 g/mL). Except the sham-operation group, the other groups were received an abdominal aorta constriction to establish a model of myocardial hypertrophy. The HW and LVW were measured to calculate the LVW/BW and HW/BW. ELISA was used to detect the serum concentration of BNP. The expressions of eNOS, TGF-1, caspase-3, VEGF, and VEGFR2 in heart tissues were assessed by western blot analysis. mRNA expressions of eNOS, Col1a1, Col3a1, TGF-1, VEGF, and VEGFR2 in heart tissues were measured by RT-PCR. The specimens were stained with hematoxylin-eosin (HE) and picrosirius red staining for observing the morphological characteristics and collagen fibers I and III of the myocardium under a light microscope.
RESULTS
LHF significantly lowered the rat's HW/BW and LVM/BW, and the level of BNP in the LHF-treated group compared with the model group. Histopathological and pathomorphological changes of collagen fibers I and III showed that LHF inhibited myocardial fibrosis in heart failure rats. Treatment with LHF upregulated eNOS expression in heart tissue and downregulated Col1a1, Col3a1, TGF-1, caspase-3, VEGF, and VEGFR2 expression.
CONCLUSION
LHF can improve left ventricular remodeling in a pressure-overloaded heart failure rat model; this cardiac protective ability may be due to cardiac fibrosis and attenuated apoptosis. Upregulated eNOS expression and downregulated Col1a1, Col3a1, TGF-1, caspase-3, VEGF, and VEGFR2 expression may play a role in the observed LHF cardioprotective effect.

Observational Study
Angiotensin-converting enzyme inhibitors, angiotensin-II-receptor antagonists and angiotensin-receptor blocker/neprilysin inhibitor utilization in heart failure patients: Sub-analysis of a nation-wide population-based study in the Czech Republic.
AIMS
Sub-analysis of a retrospective nation-wide observational analysis of heart failure (HF) epidemiology reported to the Czech National Registry of Reimbursed Health Services between 2012 and 2018 aimed at angiotensin-converting enzyme inhibitors (ACEI), angiotensin-II-receptor antagonists (ARB) and angiotensin receptor blocker/neprilysin inhibitor (ARNI) use.
METHODS AND RESULTS
ACEi and ARBs were generally used in 87.6% of all HF patients in 2012 (n=154 627); 84.5% in 2013 (n=170 861); 83.5% in 2014 (n=186 963); 81.6% in 2015 (n=198 844); 80.1% in 2016 (n=205 793); 78.0% in 2017 (n=212 152) and in 76.7% in 2018 (n=219 235). In a sub-analysis of patients with a medical procedure and/or examination using an I50.x ICD code accounted for in the given year, ACEi and ARBs were generally used in 99.3% in 2012 (n=63 250); 96% in 2013 (n=62 241); 95.2% in 2014 (n=64 414); 93.3% in 2015 (n=65 217); 91.8% in 2016 (n=65 236); 90.1% in 2017 (n=65 761) and in 88.6% in 2018 (n=66 332). In 2018, the majority of patients with HF were prescribed ramipril (n=49 909; 17.5%) and perindopril (n=44 332; 15.5%). The mostly prescribed ARBs in 2018 were telmisartan (n=18 669; 6.5%); losartan (n=13 935; 4.9%) and valsartan (n=4 849; 1.7%). In 24.5% of cases, ACEIs and ARBs were prescribed in a fixed combination with another drug. ARNI became gradually more prescribed from 2018 (n=9 659 in November 2020).
CONCLUSION
In an analysis of ACEIs, ARBs and ARNIs utilization in all patients treated for heart failure in the given year in the whole country, we found a comparable rate of drug prescription in comparison with specific heart failure registries. This indicates a good translation of current standard of care into common clinical practice. Ramipril and perindopril remained the mostly prescribed ACEIs and telmisartan became the mostly prescribed ARB. Since 2018, ARNIs began to be widely prescribed.

KEY POINTS
The arterial baroreflex's operating point pressure is reset upwards and rightwards from rest in direct relation to the increases in dynamic exercise intensity. The intraneural pathways and signalling mechanisms that lead to upwards and rightwards resetting of the operating point pressure, and hence the increases in central sympathetic outflow during exercise, remain to be identified. We tested the hypothesis that the central production of angiotensin II during dynamic exercise mediates the increases in sympathetic outflow and, therefore, the arterial baroreflex operating point pressure resetting during acute and prolonged dynamic exercise. The results identify that perindopril, a centrally acting angiotensin converting enzyme inhibitor, markedly attenuates the central sympathetic outflow during acute and prolonged dynamic exercise.
ABSTRACT
We tested the hypothesis that the signalling mechanisms associated with the dynamic exercise intensity related increases in muscle sympathetic nerve activity (MSNA) and arterial baroreflex resetting during exercise are located within the central nervous system. Participants performed three randomly ordered trials of 70° upright back-supported dynamic leg cycling after ingestion of placebo and two different lipid soluble angiotensin converting enzyme inhibitors (ACEi): perindopril (high lipid solubility), captopril (low lipid solubility). Repeated measurements of whole venous blood (n = 8), MSNA (n = 7) and arterial blood pressures (n = 14) were obtained at rest and during an acute (SS1) and prolonged (SS2) bout of steady state dynamic exercise. Arterial baroreflex function curves were modelled at rest and during exercise. Peripheral venous superoxide concentrations measured by electron spin resonance spectroscopy were elevated during exercise and were not altered by ACEi at rest (P ≥ 0.4) or during exercise (P ≥ 0.3). Baseline MSNA and mean arterial pressure were unchanged at rest (P ≥ 0.1; P ≥ 0.8, respectively). However, during both SS1 and SS2, the centrally acting ACEi perindopril attenuated MSNA compared to captopril and the placebo (P < 0.05). Arterial pressures at the operating point and threshold pressures were decreased with perindopril from baseline to SS1 with no further changes in the operating point pressure during SS2 under all three conditions. These data suggest that centrally acting ACEi is significantly more effective at attenuating the increase in the acute and prolonged exercise-induced increases in MSNA.

Randomized Controlled Trial
BACKGROUND
This trial aimed to determine the efficacy of leucine and/or perindopril in improving physical function in older people with sarcopenia.
METHODS
Placebo-controlled, parallel group, double-blind, randomized two-by-two factorial trial. We recruited adults aged ≥ 70 years with sarcopenia, defined as low gait speed (<0.8 m/s on 4 m walk) and/or low handgrip strength (women < 20 kg, men < 30 kg) plus low muscle mass (using sex and body mass index category-specific thresholds derived from normative UK BioBank data) from 14 UK centres. Eligible participants were randomized to perindopril 4 mg or placebo, and to oral leucine powder 2.5 g or placebo thrice daily. The primary outcome was the between-group difference in the short physical performance battery (SPPB) score over 12-month follow-up by repeated-measures mixed models. Results were combined with existing systematic reviews using random-effects meta-analysis to derive summary estimates of treatment efficacy.
RESULTS
We screened 320 people and randomized 145 participants compared with an original target of 440 participants. For perindopril [n = 73, mean age 79 (SD 6), female sex 39 (53%), mean SPPB 7.1 (SD 2.3)] versus no perindopril [n = 72, mean age 79 (SD 6), female sex 39 (54%), mean SPPB 6.9 (SD 2.4)], median adherence to perindopril was lower (76% vs. 96%; P < 0.001). Perindopril did not improve the primary outcome [adjusted treatment effect -0.1 points (95%CI -1.2 to 1.0), P = 0.89]. No significant treatment benefit was seen for any secondary outcome including muscle mass [adjusted treatment effect -0.4 kg (95%CI -1.1 to 0.3), P = 0.27]. More adverse events occurred in the perindopril group (218 vs. 165), but falls rates were similar. For leucine [n = 72, mean age 78 (SD 6), female sex 38 (53%), mean SPPB 7.0 (SD 2.1)] versus no leucine [n = 72, mean age 79 (SD 6), female sex 40 (55%), mean SPPB 7.0 (SD 2.5)], median adherence was the same in both groups (76% vs. 76%; P = 0.99). Leucine did not improve the primary outcome [adjusted treatment effect 0.1 point (95%CI -1.0 to 1.1), P = 0.90]. No significant treatment benefit was seen for any secondary outcome including muscle mass [adjusted treatment effect -0.3 kg (95%CI -1.0 to 0.4), P = 0.47]. Meta-analysis of angiotensin converting enzyme inhibitor/angiotensin receptor blocker trials showed no clinically important treatment effect for the SPPB [between-group difference -0.1 points (95%CI -0.4 to 0.2)].
CONCLUSIONS
Neither perindopril nor leucine improved physical performance or muscle mass in this trial; meta-analysis did not find evidence of efficacy of either ACE inhibitors or leucine as treatments to improve physical performance.

Turkish Journal of Medical Sciences Dec 2018This study aimed to investigate the effects of two different medical treatment options on choroidal thickness (CT) in patients with primary hypertension.
BACKGROUND/AIM
This study aimed to investigate the effects of two different medical treatment options on choroidal thickness (CT) in patients with primary hypertension.
MATERIALS AND METHODS
Forty newly diagnosed primary hypertension patients and 21 healthy volunteers were included. The patients were randomly divided into two subgroups. Group I started on perindopril arginine and Group II started on amlodipine. Submacular CT using optical coherence tomography (OCT) was measured before treatment and at the third and sixth months after treatment.
RESULTS
Initial mean arterial pressure (MAP) values in Groups I and II and the control group were 113.4, 109.8, and 89.4 mmHg, respectively, and mean CT values were 257.9, 286.5, and 300.9 μm. Mean MAP values in Groups I and II and the control group at the sixth month after treatment were 99.7, 99.6, and 90.2 mmHg, respectively, and mean CT values were 293.1, 286, and 297.4 μm. Analysis of the changes occurring during the study revealed significant variation in MAP in Groups I and II, and in CT in Group I only.
CONCLUSION
A gradual increase in CT developed with perindopril arginine therapy in patients with primary hypertension, while no significant change occurred in CT in the amlodipine group.

Randomized Controlled Trial
INTRODUCTION
The ORBITA trial of percutaneous coronary intervention (PCI) versus a placebo procedure for patients with stable angina was conducted across six sites in the United Kingdom via home monitoring and telephone consultations. Patients underwent detailed assessment of medication adherence which allowed us to measure the efficacy of the implementation of the optimization protocol and interpretation of the main trial endpoints.
METHODS
Prescribing data were collected throughout the trial. Self-reported adherence was assessed, and urine samples collected at pre-randomization and at follow-up for direct assessment of adherence using high-performance liquid chromatography with tandem mass spectrometry (HPLC MS/MS).
RESULTS
Self-reported adherence was >96% for all drugs in both treatment groups at both stages. The percentage of samples in which drug was detected at pre-randomization and at follow-up in the PCI versus placebo groups respectively was: clopidogrel, 96% versus 90% and 98% versus 94%; atorvastatin, 95% versus 92% and 92% versus 91%; perindopril, 95% versus 97% and 85% versus 100%; bisoprolol, 98% versus 99% and 96% versus 97%; amlodipine, 99% versus 99% and 94% versus 96%; nicorandil, 98% versus 96% and 94% versus 92%; ivabradine, 100% versus 100% and 100% versus 100%; and ranolazine, 100% versus 100% and 100% versus 100%.
CONCLUSIONS
Adherence levels were high throughout the study when quantified by self-reporting methods and similarly high proportions of drug were detected by urinary assay. The results indicate successful implementation of the optimization protocol delivered by telephone, an approach that could serve as a model for treatment of chronic conditions, particularly as consultations are increasingly conducted online.
