Proposing new lipoprotein (a) cut off value for Kazakhstan: pilot study.

Introduction: There is no consensus on the optimal concentration of lipoprotein(a) (Lp(a)) for the risk of atherosclerotic cardiovascular diseases (ASCVD) and aortic valve stenosis. In various clinical guidelines and agreed documents, the threshold level of Lp (a) is 30 mg/dl or 50 mg/dl. We estimated the cut-off value of Lp (a) associated with the risk of developing various localizations of atherosclerosis for the Central Asia, including Kazakhstani population.

Bayesian control chart using variable sample size with engineering applications.

In this study, we suggested an innovative approach by introducing an Adaptive Exponential Weighted Moving Average (AEWMA) control chart utilizing Variable Sample Size (VSS) under Bayesian methodology. The proposed methodology utilized an integer linear function to dynamically adjust sample sizes according to the AEWMA statistic. Another appealing feature of our adaptive framework is the integration of the smoothing constant of an EWMA chart, which enhances monitoring responsiveness.

Outcomes of myocardial revascularization in patients with obesity and multivessel coronary artery disease.

Background: There is uncertainty regarding the best revascularization approach-whether coronary artery bypass grafting (CABG) or percutaneous coronary intervention (PCI)-for obese patients suffering from multi-vessel coronary artery disease.

Results: 406 patients with low and intermediate SYNTAX scores (SS) underwent PCI with drug-eluting stents (n = 200, 100 with SS ≤ 22, and 100 with SS 23-32) and CABG (n = 206, 100 with SS ≤ 22, and 106 with SS 23-32). Patients were also categorized by body mass index (BMI): normal weight (12%, 48 patients), overweight (41.

Complicated catheter ablation of premature ventricular contractions from the left sinus of Valsalva in a young female. Case presentation.

Idiopathic premature ventricular complexes (PVCs) are usually benign and are often treated conservatively. Data regarding radiofrequency catheter ablation (RFA) of PVCs from the aortic sinus of Valsalva are spare. Furthermore, there are limited data regarding complications and their solutions during RFA of PVCs from the aortic sinus of Valsalva.

ALCAPA in adult asymptomatic patient: A case report.

Introduction: Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart disease that usually presents with heart failure symptoms in infants. Without surgical correction, the condition has a high infant mortality rate. However, patients with ALCAPA can remain asymptomatic for decades in some cases, and the risk of sudden death decreases in adulthood.
