Short-term dual antiplatelet therapy in diabetic patients admitted for acute coronary syndrome treated with a new-generation drug-eluting stent.

BACKGROUND: The optimal duration of dual antiplatelet therapy (DAPT) in patients with diabetes mellitus (DM) admitted with acute coronary syndrome (ACS) and treated with a drug-eluting stent (DES) remains unclear. This is a prespecified sub-study from the Randomised Evaluation of short-term DUal antiplatelet therapy in patients with acute Coronary syndromE treated with a new generation DES (REDUCE) trial that was designed to determine the efficacy and safety of short-term versus standard 12 months DAPT in diabetic patients with ACS undergoing percutaneous coronary intervention (PCI) using the COMBO stent. METHODS: In this study we included ACS diabetic patients enroled in the REDUCE trial treated with the COMBO stent and randomly assigned to either 3 or 12 months of DAPT. The primary study endpoint was the composite of all-cause mortality, myocardial infarction (MI), stent thrombosis (ST), stroke, target vessel revascularisation (TVR), and bleeding complications at 12 and 24 months follow-up. RESULTS: A total of 307 diabetic patients were included, of which 162 (52.8%) in the 3 months DAPT group and 145 (47.2%) in the 12 months DAPT group. Patient characteristics, PCI success, and number of stents used were similar in the 3 and 12 months DAPT groups. Occurrence of the primary study endpoint at 12 and 24 months follow-up was comparable between the two groups (3.1 vs. 3.5%, p = 0.865, and 15.8 vs. 14.9%, p = 0.824, respectively). Moreover, the prevalence of the specific clinical outcome parameters (all-cause mortality), MI, ST, stroke, TVR, and bleeding was similar in both study groups. CONCLUSIONS: This sub-analysis shows similar clinical outcomes following 3 months DAPT as compared to 12 months DAPT in diabetic patients undergoing PCI for ACS using the COMBO stent. These results suggest that, even in this particular subset of patients, short duration of DAPT might be considered safe. Future larger studies are warranted to provide more precise estimations in terms of safety and efficacy of short term DAPT in these high-risk patients.

LDL Cholesterol Goal Attainment in Hypercholesterolemia: CEPHEUS Indonesian Survey.

BACKGROUND: Several studies have shown that lipid-lowering therapy to address hypercholesterolemia is generally inadequate because the target cholesterol goal is not achieved. Our study reviews the cholesterol goal attainment among patients receiving lipid lowering therapy in Indonesian hypercholesterolemic patients. METHODS: This surveywas part of the Pan-Asian CEPHEUS (CEntralized Pan-Asian survey on tHE Under-treatment of hypercholeSterolemia) study, involving hypercholesterolemic patients ≥ 18 years of age, who were on lipid- lowering treatment for ≥ 3 months. Lipid concentrations were measured, demographic and other clinically relevant information were collected. Definitions and criteria set by the updated 2004 National Cholesterol Education Program - Adult Treatment Program III was applied. RESULTS: In this survey, 149 physicians enrolled 979 patients, of whom only 834 were included in the final analysis. The mean age was 56.5 years, 53.5% male, and 82.3% were on statin monotherapy. The LDL-C goal attainment rate amongst Indonesians (31.3%)was belowthat of the overall Asian rate (49.1%). The lowest attainment (12.1%)was found in patients with a therapeutic target < 70 mg/dL. Additionally, the goal attainment rate in patients with metabolic syndrome (28%) was significantly lower than in patients without metabolic syndrome (37.5%, p = 0.006). Goal attainment was inversely related to cardiovascular risk and baseline LDL-C (p < 0.001). It was also noted that approximately 65.1% of patients believed he/she could miss a dosage without affecting his/her blood cholesterol concentration. CONCLUSIONS: High proportions of Indonesian hypercholesterolemic patients on lipid-lowering drug are not at the recommended LDL-C levels, and remain at risk for cardiovascular disease. KEY WORDS: Cardiovascular disease; Dyslipidemia; Hypercholesterolemia; Indonesian; LDL cholesterol.

Effects of coenzyme Q10 supplementation on diastolic function in patients with heart failure with preserved ejection fraction.

Heart failure with preserved ejection fraction (HFpEF) is a leading cause of morbidity and mortality without an established treatment. Diastolic dysfunction, the hallmark of HFpEF, is associated with altered myocardial bioenergetics. No previous study has examined the effects of coenzyme Q10 (CoQ10) on left ventricle (LV) diastolic function in patients with HFpEF. We investigated whether CoQ10 could improve LV diastolic function in patients with HFpEF. We performed a randomized controlled trial (RCT) using pretest and posttest control groups of 30 patients with HFpEF. The patients received either CoQ10 100 mg three times a day or no CoQ10 in addition to routine treatment for 30 days. Echocardiographic study was performed at baseline and follow-up. LV diastolic function was evaluated by two dimensional and Doppler echocardiography as follows; average E/e׳, septal and lateral e׳velocity, and left atrium volume index (LAVI). A total of 28 patients completed the study. A statistically significant improvement was observed in the CoQ10 treatment group in terms between groups (∆E/e׳ ‒ 3.6 vs. ‒ 2.4; p = 0.28) and (∆LAVI ‒ 5.4 vs. ‒ 4.4; p = 0.83). Short term CoQ10 supplementation provided no additional benefits in improving LV diastolic function in patients with HFpEF.

Carotid Intima-Media Thickness in Indonesian Subjects with Cardiovascular Disease Risk Factors Who Were Not Receiving Lipid-Lowering Agents.

Carotid intima-media thickness (CIMT) is frequently utilized for detection of subclinical atherosclerosis. This study aims to investigate the association between the CIMT values and demographic characteristics, cardiovascular disease (CVD) risk factors, lipid biochemistry profiles, and high-sensitivity C-reactive protein (hs-CRP) levels among the Indonesian population. Subjects who had two or more CVD risk factors but were not receiving lipid-lowering therapy were recruited from six hospitals of Indonesia. Measurements of CIMT are obtained by ultrasonography of 12 sites within the common carotid artery. CVD risk factors, lipid and glucose profiles, and hs-CRP values were analyzed with respect to distribution of CIMT. The mean-max CIMT was 0.805 ± 0.190 mm (minimum, 0.268 mm; maximum, 1.652 mm) and the mean-mean CIMT was 0.614 ± 0.190 mm (minimum, 0.127 mm; maximum, 1.388 mm). Multivariate analyses confirmed an independent association between increasing CIMT and increasing age (regression coefficient = 0.004; p = 0.004). Our data show normative mean-mean CIMT data for Indonesian subjects with two or more CVD risk factors who are not receiving lipid-lowering therapy, which may guide CVD risk stratification of asymptomatic individuals in Indonesia.
