Introduction The V-GOOD study evaluated the effectiveness of trimetazidine modified-release (MR) 80 mg once daily (OD) in patients with chronic coronary syndrome (CCS) who remained symptomatic despite antianginal therapies in routine clinical practice. Methods This prospective, observational study involved 1026 adult outpatients with symptomatic CCS from 70 sites in Brazil who were prescribed trimetazidine MR 80 mg OD plus background antianginal treatment. Data on number of angina attacks, short-acting nitrate consumption, prevalence of angina-free patients, severity of angina, patient-reported daily physical activity impairment, treatment adherence, tolerability, and cardiologist and patient satisfaction were collected at baseline (V1), then at 1 month (V2) and 3 months (V3). Results Following the addition of trimetazidine MR 80 mg OD, the mean ± standard deviation number of angina attacks per week decreased from 3.1 ± 2.8 at V1 to 1.0 ± 2.1 at V2, and 0.7 ± 1.7 at V3, with concurrent reductions in short-acting nitrate consumption, patient-reported daily physical activity impairment and the proportion of patients with limiting angina (Canadian Cardiovascular Society class III or IV), and increases in the proportion of angina-free patients (all p < 0.001 vs. V1). Most cardiologists rated trimetazidine MR 80 mg OD as satisfactory/very satisfactory (90.7% for effectiveness and 94.8% for tolerability); most patients rated the treatment schedule as convenient/very convenient (97.2%) and satisfactory/very satisfactory (97.1%). Treatment was well tolerated. Conclusions These data support the symptomatic benefits and good tolerability associated with adding trimetazidine MR 80 mg OD to other antianginal therapies in patients with persistent symptoms.

Recent studies have found increased cardiovascular mortality risk in patients with type 1 diabetes when compared to normoglycemic people, even when they were kept under good glycemic control. However, the mechanisms underlying this condition have yet to be fully understood. Using streptozotocin (STZ)-induced diabetic rats, we evaluated the effects of insulin replacement therapy on cardiac, autonomic, inflammatory, and oxidative stress parameters. Daily treatment with insulin administrated subcutaneously in the STZ-diabetic rats showed a reduction in hyperglycemia (>250 mg/dL) to normalized values. The insulin treatment was effective in preventing alterations in cardiac morphometry and systolic function but had no impact on diastolic function. Also, the treatment was not able to prevent the impairment of baroreflex-tachycardic response and systolic arterial pressure variability (SAP-V). A correlation was found between improvement of these autonomic parameters and higher levels of IL-10 and lower levels of oxidized glutathione. Our findings show that insulin treatment was not able to prevent diastolic, baroreflex, and SAP-V dysfunction, suggesting an outstanding cardiovascular risk, even after obtaining a good glycemic control in STZ-induced diabetic rats. This study shed light on a relatively large population of diabetic patients in need of other therapies to be used in combination with insulin treatment and thus more effectively manage cardiovascular risk.

Dyslipidemia is related to the progression of atherosclerosis and is an important risk factor for acute coronary syndromes. Our objective was to determine the effect of rosuvastatin on myocardial necrosis in an experimental model of acute myocardial infarction (AMI). Male Wistar rats (8-10 weeks old, 250-350 g) were subjected to definitive occlusion of the left anterior descending coronary artery to cause AMI. Animals were divided into 6 groups of 8 to 11 rats per group: G1, normocholesterolemic diet; G2, normocholesterolemic diet and rosuvastatin (1 mg·kg(-1)·day-1) 30 days after AMI; G3, normocholesterolemic diet and rosuvastatin (1 mg·kg(-1)·day-1) 30 days before and after AMI; G4, hypercholesterolemic diet; G5, hypercholesterolemic diet and rosuvastatin (1 mg·kg(-1)·day-1) 30 days after AMI; G6, hypercholesterolemic diet and rosuvastatin (1 mg·kg(-1)·day-1) 30 days before and after AMI. Left ventricular function was determined by echocardiography and percent infarct area by histology. Fractional shortening of the left ventricle was normal at baseline and decreased significantly after AMI (P < 0.05 in all groups), being lower in G4 and G5 than in the other groups. No significant difference in fractional shortening was observed between G6 and the groups on the normocholesterolemic diet. Percent infarct area was significantly higher in G4 than in G3. No significant differences were observed in infarct area among the other groups. We conclude that a hypercholesterolemic diet resulted in reduced cardiac function after AMI, which was reversed with rosuvastatin when started 30 days before AMI. A normocholesterolemic diet associated with rosuvastatin before and after AMI prevented myocardial necrosis when compared with the hypercholesterolemic condition.

Introduction: Ventricular arrhythmias may lead to sudden cardiac death and, when occurring during the recovery phase after exercise testing, are associated with increased cardiovascular risk. Aim: To investigate the association between psychosocial stress and the risk of premature ventricular contractions (PVCs) during the recovery phase after treadmill testing in asymptomatic individuals. Methods: A total of 282 asymptomatic adults underwent treadmill testing. Participants were categorized into a stress-present group (+S, n = 176) or a stress-absent group (−S, n = 106) based on their self-reported psychosocial stress levels. Inclusion criteria included exercising for at least 6 min and reaching at least 85% of the age-predicted maximum heart rate. Exclusion criteria comprised pre-exercise VAs, unreadable ECGs, chronic medication use, systolic blood pressure ≥180 mmHg, and diastolic blood pressure ≥110 mmHg. This study was registered on ClinicalTrials.gov (NCT05987891). Results: Compared to the −S group, the +S group had a higher body mass index (BMI) (p = 0.0025); 26.5 (23.9; 29.0) and larger waist circumference (p = 0.0001); 95 (86; 103), and reported lower physical activity levels (p = 0.0004). Notably, only psychosocial stress and BMI were statistically associated with PVCs during the recovery phase, immediately following the stress test. For each 1 kg/m² increase in BMI, the risk of PVCs decreased by 9%. Participants reporting psychosocial stress had a 9.03-fold higher risk of PVCs compared to those who did not report stress. Conclusions: Self-reported psychosocial stress significantly increases the risk of PVC occurrence during the recovery phase of treadmill exercise testing in asymptomatic individuals. These findings may support the development of improved PVC detection strategies and enhance cardiovascular risk assessment in clinical settings.

Background/Objectives: The guideline targets for blood pressure (BP), hemoglobin A1c (HbA1c), and low-density lipoprotein cholesterol (LDL-C) are frequently unmet, and physicians often misjudge control. This study aimed to characterize the real-world control of BP, HbA1c, and LDL-C in patients with type 2 diabetes (T2D) and hypertension, herein called cardiometabolic multimorbidity (CMM), and to compare guideline-based versus physician-perceived disease control. Methods: We conducted SNAPSHOT–Brazil, a nationwide, multicenter, cross-sectional study to gather real-world data on patients with CMM. The ESC guidelines defined the cardiovascular (CV) risk and control targets. Results: We included 451 patients with hypertension and T2D (median age 65 years; 60% female; 54% White). Most patients (98%) were on pharmacotherapy and reported high adherence (according to the Hill–Bone Medication Adherence Scale). A very high CV risk predominated (78%); 22% of the patients were at a high risk. The guideline-defined control was achieved in 27% for BP, 34% for HbA1c, 13% for LDL-C, and 6% for both BP and LDL-C; only 3% met all three targets simultaneously. The physicians accurately stratified the CV risk in 49% of patients, while 50% had their CV risk underestimated. They systematically overestimated control in 29% of cases for BP, 35% for LDL-C, and 25% for both. The sensitivity ranged from 0.88 to 0.98; the positive predictive values ranged from 0.19 to 0.48, and the positive likelihood ratios ranged from 2.16 to 3.65. Conclusions: The SNAPSHOT–Brazil study revealed a low attainment of BP, HbA1c, and LDL-C targets, despite the widespread pharmacotherapy and the high self-reported adherence. The physicians consistently overestimated disease control and underestimated the CV risk.
