Medical and advanced heart failure therapies in Türkiye

Effective management of heart failure involves evidence-based use of multiple medications and their combinations. Furthermore, dosage escalation of the recommended medications is advised. In cases of advanced heart failure, long-term mechanical assistance devices or heart transplantation surgery may be necessary. Socio-economic disparities create unequal opportunities for people to access these treatments.The study aimed to analyze and compare medical and advanced heart failure treatments recommended by guidelines across various regions in Türkiye.

About 85 million citizens medical treatment records were utilized between January 1, 2016, and December 31, 2022. Medical and heart replacement treatment opportunities for heart failure in Türkiye were evaluated in the general population and across different geographical regions.

According to this study, beta-blockers were the most commonly prescribed medication for heart failure in Türkiye. This was followed by angiotensin-converting enzyme inhibitors at 44% and mineralocorticoid receptor antagonists at 38.9%. However, only 0.6% of patients used angiotensin receptor blocker-neprilysin inhibitors. Despite the high incidence of diabetes mellitus among heart failure patients, only 11% used sodium-glucose cotransporter two inhibitors. The study also found that using an implantable cardioverter defibrillator (ICD) was 0.8%, and cardiac resynchronization therapy (CRT) was 0.3% among all intracardiac device treatments. Heart replacement therapies, cardiac transplantation surgery, and long-term left ventricle-assisted device (LVAD) surgery had very low rates.

The use of guideline-directed medical therapy is not optimal in Türkiye and varies across different geographical regions. It is a fact that heart transplant or LVAD surgery, CRT, and ICD implantation rates in Türkiye are significantly lower than those in developed countries, regardless of geographical region.
