Analysis of Cardiac Events and the Subsequent Impact for Geriatric Patients Undergoing Hip Fracture Surgeries.

Perioperative complications, particularly cardiac events, compromised surgical outcomes for geriatric patients. This retrospective study intended to investigate the occurrence and subsequent impact of cardiac events for geriatric patients undergoing hip fracture surgeries. We collected 607 patients undergoing hip fracture surgeries from January 2017 to December 2022 that received transthoracic echocardiography (TTE) pre-operatively to screen for cardiac abnormalities.

Clinical Significance of Electronegative Low-Density Lipoprotein Cholesterol in Atherothrombosis.

Despite the numerous risk factors for atherosclerotic cardiovascular diseases (ASCVD), cumulative evidence shows that electronegative low-density lipoprotein (L5 LDL) cholesterol is a promising biomarker. Its toxicity may contribute to atherothrombotic events. Notably, plasma L5 LDL levels positively correlate with the increasing severity of cardiovascular diseases.

Pulmonary hypertension in patients on chronic hemodialysis and with heart failure.

Pulmonary hypertension (PH) is linked to chronic kidney disease. However, few studies have examined the prevalence, risk factors, or outcomes of PH in patients with chronic hemodialysis and concomitant heart failure. This retrospective cohort study enrolled 160 patients with a history of acute decompensated heart failure after maintenance hemodialysis therapy.

A xanthine-derivative K(+)-channel opener protects against serotonin-induced cardiomyocyte hypertrophy via the modulation of protein kinases.

This study investigated whether KMUP-1, a xanthine-derivative K(+) channel opener, could prevent serotonin-induced hypertrophy in H9c2 cardiomyocytes via L-type Ca(2+) channels (LTCCs). Rat heart-derived H9c2 cells were incubated with serotonin (10 μM) for 4 days. The cell size increased by 155.

Comparison of automated 4D-MSPECT and visual analysis for evaluating myocardial perfusion in coronary artery disease.

The aim of this study was to assess the reproducibility and diagnostic performance for coronary artery disease (CAD) of an automated software package, 4D-MSPECT, and compare the results with a visual approach. We enrolled 60 patients without previously known CAD, who underwent dual-isotope rest Tl-201/stress Tc-99m sestamibi myocardial perfusion imaging and subsequent coronary angiography within 3 months. The automated summed stress score (A-SSS), summed rest score (A-SRS) and summed difference score (A-SDS) were obtained using a 17-segment five-point scale model with 4D-MSPECT.

The association of silent coronary artery disease and metabolic syndrome in Chinese with type 2 diabetes mellitus.

Objectives: Cardiovascular diseases account for approximately 75% of the deaths that occur in patients with diabetes. Because the clinical signs of coronary artery disease (CAD) in diabetic patients are hard to detect and routine screening is costly, it would be of great benefit to try to either prevent CAD from occurring or to detect it early and provide optimal care. Therefore, we analyzed the risk factors that might predict CAD in type 2 diabetes mellitus (T2DM) patients with no classical cardiac ischemic symptoms.

Differential effects of adenosine on antegrade fast pathway, antegrade slow pathway, and retrograde fast pathway in atrioventricular nodal reentry.

Adenosine has a potent negative dromotropic effect. However, comparative effects of adenosine on the three pathways of atrioventricular (AV) nodal reentry remain unclear. In this study, we sought to determine the effects of adenosine on the antegrade fast, antegrade slow, and retrograde fast pathway conduction in patients with AV nodal reentrant tachycardia (AVNRT).

Simple Way to Resolve the Range Ambiguity.

PURPOSE: The purpose of this study was to test the hypothesis that with the range gate fixed, random adjustment of the pulse repetition frequency will offer a rapid and accurate way to avoid misinterpretation of range ambiguity. BACKGROUND: Traditionally, to avoid the misdiagnosis of Doppler artifacts caused by range ambiguity, time must be spent on checking the flow patterns in the calculated phantom range gates. METHODS: Twenty-four patients (mean age 64 +/- 15 years, 15 men and nine women) with mitral regurgitation were included in the study.
