A retrospective audit of young adults who received permanent pacemakers at a teaching hospital in the Western Cape, South Africa

Frontiers in Cardiovascular Medicine, 2023
IntroductionWhile most pacemaker implantations occur in older individuals, younger patients also receive pacemakers. In these, degenerative conduction system disease is less likely to be the cause of atrioventricular block (AVB), with other diseases ...

Prognostic Value of the Global Left Ventricular Contractility Index in Patients with Severe Mitral Regurgitation and Preserved Left Ventricular Ejection Fraction

Journal of Cardiovascular Development and Disease
Introduction: Assessment of left ventricular (LV) systolic function is important in valvular heart disease. The global LV contractility index, dσ*/dtmax, is load-independent and has been reported to be associated with clinical outcomes in heart failure ...
