Prognostic significance of right ventricular dysfunction in patients presenting with acute left-sided heart failure.

BACKGROUND: The prognostic value of right ventricular (RV) function in chronic heart failure (HF) has lately been well established. However, research on its role in acute heart failure (AHF) is sparse. RESULTS: This study comprised 195 patients, aged between 18 and 80 years, with acute left-sided heart failure (HF) and a left ventricular ejection fraction (LVEF) < 50%. Patients with LVEF ≥ 50%, mechanical ventilatory or circulatory support, poor echocardiographic windows, prosthetic valves, congenital heart diseases, infective endocarditis, and/or life expectancy < 1 year due to non-cardiac causes were excluded. The study participants' mean age was 57.7 ± 10.9 years, and 74.9% were males. Coronary artery disease was present in 80.5% of patients. The mean LVEF was 31% ± 8.7. RV dysfunction (RVD), defined as tricuspid annular plane systolic excursion (TAPSE) < 17 mm, RV S' < 9.5 cm/s and/or RV fractional area change (FAC) < 35%, was identified in 48.7% of patients. The RV was dilated in 67.7% of the patients. RVD was significantly associated with a longer HF duration, atrial fibrillation, and idiopathic dilated cardiomyopathy. The primary outcome, a 6-month composite of cardiovascular death or hospitalization for worsening HF (HHF), occurred in 42% of the participants. Cardiovascular mortality and HHF occurred in 30.5% and 23.9% of the patients, respectively. The primary endpoint and longer CCU stays were significantly more common in patients with RVD than in those with normal RV function. RV dilatation was significantly associated with the primary outcome, whether alone or in combination with RVD. Multivariate regression analysis showed that only RV global longitudinal strain (GLS) independently predicted poor outcomes. CONCLUSIONS: RVD and RV dilatation strongly predict CV death and HHF in patients with AHF and LVEF < 50%. Multivariate analysis showed that RV GLS was the only predictor of a composite of CV death and HHF.

Insights from Egyptian ticagrelor study in patients who presented with acute coronary syndrome (ETS in ACS).

BACKGROUND: Dual antiplatelet therapy with aspirin and a thienopyridine is used to prevent thrombotic complications of acute coronary syndrome (ACS) and percutaneous coronary interventions (PCI). Ticagrelor is an oral, reversible inhibitor of the adenosine diphosphate receptor P2Y12 with a faster onset and more potent platelet inhibition than clopidogrel. A study was needed to evaluate the efficacy and safety of generic ticagrelor in Egyptian patients. RESULTS: This multicenter study included 830 patients aged above 40 years and diagnosed with ACS, with or without ST segment elevation during the preceding 6 months. They received generic ticagrelor (Thrombolinta, Global Napi Pharmaceutical Company, Egypt) (180 mg loading dose, 90 mg twice daily thereafter), added to aspirin 75-100 mg daily. The mean age of our study population was 57.5 (8.3) years and 38.3% were females. Hypertension, diabetes mellitus, dyslipidemia and previous coronary revascularization were present in 70.7%, 59.2%, 80.7% and 31% of the patients, respectively, and 42.5% were current smokers. The qualifying event was unstable angina, non-ST segment elevation myocardial infarction and ST segment elevation myocardial infarction in 54%, 21.8% and 24.2% of the patients, respectively. At 6 months, the primary efficacy end point-a composite of cardiovascular death, myocardial infarction and stroke-occurred in 3.4% of patients, while the secondary efficacy endpoint-a composite of the primary efficacy endpoints with the addition of hospitalization for unstable angina and urgent revascularization-occurred in 15.3%. Cardiovascular death occurred in 1.2% of the patients, myocardial infarction in 0.8%, stroke in 1.3%, hospitalization for UA in 8.1% and urgent revascularization in 3.9%. TIMI major bleeding occurred in 1.2% of patients, intracranial hemorrhage in 0.2% and TIMI minor bleeding in 13.3%. No significant difference was found between patients who underwent PCI at baseline and those who were treated conservatively regarding the primary (14 patients in each group, P = 0.931) and secondary (62 vs. 65 patients, P = 0.946) efficacy endpoints. CONCLUSIONS: In patients who had an ACS during the 6 months preceding enrollment, treatment with generic ticagrelor led to a low rate of cardiovascular death, myocardial infarction and stroke with a minor increase in the risk of major bleeding.

Egyptian practical guidance in hypertriglyceridemia management 2021.

Hypertriglyceridemia (HTG) is a very common, yet underappreciated problem in clinical practice. Elevated triglyceride (TG) levels are independently associated with atherosclerotic cardiovascular disease (ASCVD) risk. Furthermore, severe HTG may lead to acute pancreatitis. Although LDL-guided statin therapy has improved ASCVD outcomes, residual risk remains. Recent trials have demonstrated that management of high TG levels, in patients already on statin therapy, reduces the rate of major vascular events. Few guidelines were issued, providing important recommendations for HTG management strategies. The goal of treatment is to reduce the risk of ASCVD and acute pancreatitis. The management stands on lifestyle modification, detection of secondary causes of HTG and pharmacological therapy, when indicated. In this guidance we review the causes and classification of HTG and summarize the current methods for risk estimation, diagnosis and treatment. The present guidance provides a focused update on the management of HTG, outlined in a simple user-friendly format, with an emphasis on the latest available data.

Correlation of echocardiographic parameters in prone and supine positions in normal adults using a novel approach.

BACKGROUND: Transthoracic echocardiography (TTE) in prone position is challenging. Innovative use of transesophageal echocardiography (TEE) probe to perform TTE for such patients has been described; but reproducibility and correlation of the TTE measurements by this technique with those obtained by the standard supine TTE study are still unknown. METHODS: We enrolled 30 non-COVID-19 individuals, with a mean (SD) age 35 (10.9) years and 11 females, to study the agreement between the transthoracic measurements of the left ventricular (LV), left atrial (LA), aortic dimensions, and ejection fraction (EF) obtained in prone position using an external TEE probe versus the standard supine position using the conventional TTE probe. RESULTS: There were no significant differences between LV end-diastolic and end-systolic diameters, septal wall thickness, posterior wall thickness, and aortic root dimensions in the prone versus the supine positions, while the mean EF (60.3% vs 63.1%, P = .014) and mean LA dimensions (1.8 vs 1.9 cm/m2 , P < .001) were significantly lower in the prone position. The mean time of scans was significantly longer in the prone as compared to the supine position (12.5 vs 4.5 minutes, P < .001). All supine studies had good quality while in the prone position four studies were of poor quality, and one was nondiagnostic. CONCLUSIONS: Assessment of cardiac dimensions and systolic function in the prone position using transthoracic TEE probe was feasible. LV and aortic dimensions agreed well with the standard TTE in supine position; however, LA dimensions and EF were lower in the prone position.

Egyptian practical guidance in lipid management 2020.

BACKGROUND: Numerous epidemiological investigations and randomized clinical studies have determined that dyslipidemia is a major contributor to atherosclerotic cardiovascular disease (ASCVD). Consequently, the management of serum cholesterol and low-density lipoprotein levels has become a central objective in the effort to prevent cardiovascular events. MAIN BODY: Many guidelines were issued by different organizations and societies to define patient risk and establish important recommendations for management strategies. Newer cholesterol-lowering agents (non-statin drugs) are described, and their use is directed primarily to secondary prevention in patients at very high risk of new ASCVD. CONCLUSION: The present guidance summarizes the current methods for risk estimation and outlines the most recent data on lipid management in a simple user-friendly format, to improve physician awareness and help implement guidelines in the daily practice.
