“…Second, the risk of SCD and ICD shocks has been largely based on populations from the 1990s and early 2000s but there has been an almost 70% reduction of mortality in patients with coronary artery disease and heart failure in the last 20 years and a 44% reduction in SCD rates between 1995 and 2014 in patients with heart failure and reduced ejection fraction. [27,28] These dramatic changes were a result of more effective drug treatment, e.g. angiotensin converting enzyme inhibitors, early revascularisation in patients with acute coronary syndromes, implementation of cardiac resynchronisation therapy, and so on.…”
