THE LIPID PARADOX IN POSTOPERATIVE ATRIAL FIBRILLATION
The combination of abdominal obesity and elevated triglycerides (TG), i.e. hypertriglyceridemic waist, is a known risk factor for coronary heart disease. Abdominal adiposity is also known to increase the risk of atrial fibrillation (AF). Yet, a lipid paradox has been described, where lower levels of low-density lipoproteins (LDL) and TG were associated with a higher risk of AF.
FOCUS GROUP: IMPROVING THE KNOWLEDGE OF PATIENTS ON WOMEN'S HEART HEALTH SELF-CARE MANAGEMENT
Spontaneous coronary artery dissection (SCAD), myocardial infarction with non-obstructive coronary arteries (MINOCA) disease and angina with non-obstructive coronary artery disease (ANOCA) are more prevalent in women than in men. In addition, microvascular dysfunction, one of the causes of MINOCA and ANOCA, is associated with higher rates of myocardial infarction and death in women.
Increased mortality and intervention delay in female patients with severe aortic stenosis and reduced ejection fraction undergoing aortic valve replacement
Background Women with severe aortic stenosis (AS) exhibit increased mortality after aortic valve replacement (AVR). They also tend to be operated at a more advanced stage of their valvular disease. However, this sex discrepancy in surgical referral and its impact on mortality has not been previously studied in patients with low ejection fraction (LVEF).
IMPACT OF SEMI-SUPINE STRESS ECHOCARDIOGRAPHY ON THERAPEUTIC DECISION MAKING IN PATIENTS WITH VALVULAR HEART DISEASE
Stress echocardiography (SE) has long been established to help in the diagnostic and prognostic evaluation of ischemic heart disease (IHD). However, it is not widely used in the evaluation of non-ischemic heart disease (NIHD). The semi-supine bicycle SE allows for serial evaluation of the valvular and myocardial at different exercise intensity levels. The goal of our study was to evaluate the impact of semi-supine bicycle SE on the clinical management of patients with NIHD.
EFFECT OF MYOCARDIAL INFARCTION ON AORTIC STENOSIS PROGRESSION
Factors influencing aortic stenosis (AS) progression are poorly understood. AS and coronary artery disease (CAD) are often concomitant and have common risk factors. Myocardial infarction (MI) has been shown to induce fibrotic remodeling of the mitral and tricuspid valve tissue. It is not known if these changes affect the aortic valve as well, and the impact of MI on AS progression has never been studied. The objective of this study was to examine the effect of MI on AS progression.
ECHOCARDIOGRAPHIC PREDICTORS OF MITRAL TRANSVALVULAR GRADIENTS AFTER MITRACLIP INSERTION
The percutaneous MitraClip system is recognized as a valuable alternative to surgery in patients with symptomatic mitral regurgitation (MR) and prohibitive surgical risk. However, the MitraClip procedure may lead to a reduction in the mitral valve orifice area (MVOA) and increased transmitral mean gradients (TMG).
INCREASED MORTALITY IN WOMEN WITH SEVERE AORTIC STENOSIS AND LOW EJECTION FRACTION
Women with severe aortic stenosis (AS) tend to be operated at a more advanced stage of their valvular heart disease. They also have worse survival after aortic valve replacement (AVR). This difference between sexes in surgical referral and its relationship to mortality have not been previously studied in patients with severe AS and low left ventricular ejection fraction (LVEF).
