Filter by:Following myocardial infarction, female individuals demonstrate a poorer prognosis, characterized by elevated rates of mortality and heart failure. A primary hypothesis suggests unfavorable cardiac remodeling in women. This remodeling, defined as alterations in cardiac size and shape post-infarction, necessitates repeated non-invasive imaging for study.
To evaluate the efficacy of SGLT2 inhibitors on left ventricular global longitudinal strain and diastology parameters among diabetic and non-diabetic patients with chronic heart failure
Heart failure (HF) is the most common nosology encountered in clinical practice. Its incidence and prevalence increase exponentially with increasing age and it is associated with the increased mortality, more frequent hospitalization and decreased quality of life. An initial approach to the treatment of HF patients with reduced left ventricular (LV) systolic function and left bundle branch block (LBBB) was implantation of device for cardiac resynchronization therapy using biventricular pacing. This has resulted in long-term clinical benefits such as improved quality of life, increased functional capacity, reduced HF hospitalizations and overall mortality. However, conventional cardiac resynchronization therapy (CRT) is effective in only 70% of patients. And the remaining 30% of patients are non-responders to conventional CRT. Cardiac conduction system pacing is currently a promising technique for these patients. Particularly, His bundle pacing (HBP) has been developed to achieve the same results. According to other studies HBP has shown greater improvement in hemodynamic parameters comparing with conventional biventricular CRT. But, nevertheless, there are significant clinical troubles with HBP, especially high pacing threshold. In this regard, in 2017, the left bundle branch pacing (LBBP) was developed, which demonstrated clinical advantages compared to conventional biventricular CRT. Also, since 2019, left bundle branch pacing-optimized CRT (LBBPO CRT) has been used in clinical practice. These methods have become an alternative to HBP due to the stimulation of LBB outside the blocking site, a stable pacing threshold and a narrow QRS complex duration on electrocardiogram. A series of case reports and observational studies have demonstrated the efficacy and safety of LBBP and LBBPO CRT in patients with CRT indications. However, it is not enough data about impact of CRT with LBBP and combined CRT with LBBP and LV pacing on myocardial remodeling, reducing mortality and complications. According to our hypothesis, CRT with LBBP and combined CRT with LBBP and LV pacing compared with conventional biventricular pacing will significantly improve the clinical outcomes and reverse myocardial remodeling in patients who are non-responders to biventricular CRT with HF, reduced LV ejection fraction and with indications to CRT devices with defibrillator function (CRT-D) or one of the CRT-D leads replacement.
The goal of this study is to investigate the genetic and gender specific differences, in patients with low flow low gradient aortic stenosis and high flow high gradient aortic stenosis. Patients referred for surgical aorticvalve replacement will be offered to participarte in the study. The main questions the study aims to answer are: 1. Low-gradient aortic stenosis is associated with differences in valvular concentration of the genes that code for mast-cell chymase, Angiotensin-II, ACE, ACE2 and Angiotensin receptor 1 and 2. 2. Low-gradient aortic stenosis is associated with differences in the genetic code of renin-angiotensin-aldosterone system. 3. Gender differences in LV remodelling associates with different levels of sexual hormones. Patients participating in the study will be asked to undergo: - Cardiac ultrasound, MR- and CT-scan prior to surgery - Blooddraw prior to surgery. - Heartmuscle biopsy during surgery - Cardiac MR-scan 1 year after surgery.
To explore the protective effect of prostaglandin sodium on coronary microcirculation function and ventricular remodeling after reperfusion treatment of acute ST-segment elevation myocardial infarction.
failure of closure of the ductus arteriosus after birth results in a congenital anomaly known as patent ductus arteriosus. The large ductus can induce left side heart remodeling changes which could interfere with the normal cardiac function.
The primary objective of the PERI-STEMI trial is to assess whether sacubitril-valsartan is more effective in preventing adverse LV remodeling for patients with ST-elevation myocardial infarction (STEMI) than enalapril.
Study will investigate & compare the left ventricular remodeling & systolic function between two groups of ST-elevation myocardial infarction undergoing primary per-cutaneous coronary intervention applying ischemic post-conditioning to one of them.
- To detect long-term effects of left ventricular remodeling in STEMI patients undergoing PPCI. - And to evaluate outcome.
Left ventricular (LV) remodeling following myocardial infarction (MI) is an established prognostic factor for adverse cardiovascular events and the leading cause of heart failure. Empirical observations suggests that Baduanjin exercise, an important component of traditional Chinese Qigong, exert potential impacts on cardiopulmonary function. However, the impact of a Baduanjin exercise-based cardiac rehabilitation program for patients recovering from recent MI has yet to be assessed. The aim of this trail is to evaluate whether Baduanjin exercise would prevent the maladaptive progression to adverse LV remodeling in patients following MI.
