Objective: To assess the relationship between the lipid profile, other cardiovascular risk factors and left ventricular hypertrophy (LVH) in black hypertensive patients.
Materials And Methods: We undertook a cross-sectional study of a case series at the hypertension clinic, University of Kinshasa Hospital. Lipids, lipoproteins and other cardiovascular risk factors were analysed in 100 consecutive hypertensive patients. Left ventricular hypertrophy was assessed by 12-lead electrocardiography (ECG) using Cornell voltage index.
Results: Forty-eight hypertensive patients, 26 men and 22 women, had LVH. With univariate analysis, the patients with LVH were older (age 52 +/- 9 vs 45 +/- 9 years; p /= 1.03 mmol/l (adjusted OR 0.19; 95% CI: 0.057-0.651), plasma glucose >/= 6.11 mmol/l (adjusted OR 0.19; 95% CI: 0.046- 0.828), or on treatment for hypertension (adjusted OR 0.23; 95% CI: 0.082-0.645) had a lower risk for cardiac damage compared to their respective control groups.
Conclusion: LVH is a common complication in Congolese hypertensives. Dyslipidaemia, high plasma glucose levels, the duration of hypertension and being on antihypertensive therapy appear to be the main predictors of hypertensive cardiac damage.

Right ventricular myocardial infarction (RVMI) is a significant and distinct form of acute myocardial infarction associated with considerable morbidity and mortality. It occurs most commonly due to proximal right coronary artery obstruction, often in conjunction with inferior myocardial infarction. RVMI poses unique diagnostic and therapeutic challenges due to the anatomical and functional differences between the right and left ventricles.

Objective: To investigate the effects and mechanisms of miRNA 221 on myocardial ischemia/reperfusion injury (MIRI) in mice through the regulation of phospholamban (PLB) expression.
Methods: The MIRI mouse model was created and mice were divided into sham, MIRI, MIRI+ 221, and MIRI+ scr groups, with miRNA 221 overexpression induced in the myocardium of MIRI mice by targeted myocardial injection. Quantitative RT-PCR analysis was performed to observe the variation in miRNA 221, PLB, SERCA2, RYR2, NCX1, Cyt C and caspase 3 mRNA levels in myocardium, while Western blot assessed the levels of PLB, p-PLB (Ser16), p-PLB (Thr17), SERCA2, RYR2, NCX1, Cyt C and caspase 3 proteins.

Hypertrophic cardiomyopathy (HCM), including obstructive HCM and non-obstructive HCM, can lead to sudden cardiac arrest in adolescents and athletes. Early diagnosis and treatment through auscultation of different types of HCM can prevent the occurrence of malignant events. However, it is challenging to distinguish the pathological information of HCM related to differential left ventricular outflow tract pressure gradients.

Atrial fibrillation (AF) ablation is associated with a lower likelihood of death and surgical heart failure (HF) interventions in patients with HF. This effect is mainly driven by reduced all cause and cardiovascular death following ablation. Ablation also results in improved left ventricular (LV) function, decreased AF burden and AF regression.

The Berlin Heart EXCOR is a pulsatile paracorporeal ventricular assist device (VAD) for neonates, infants, children and adults with congenital or acquired severe ventricular dysfunction. Berlin Heart EXCOR VADs are routinely used as either a bridge to a cardiac transplantation, or occasionally as a bridge to ventricular recovery. Our programmatic philosophy is to bridge neonates and infants with functionally univentricular ductal-dependent systemic circulation or functionally univentricular ductal-dependent pulmonary circulation who are at high risk for staged palliation because of important cardiac risk factors with a single-ventricle VAD (sVAD) as a bridge to a cardiac transplant.
