Five other clinical parameters along with LVEF can predict Cardiac Arrest
A recent study published in the Journal of the American College of Cardiology suggests that the prevalence of out-of-hospital cardiac arrest (OHCA) 90 days after Myocardial Infarction (MI) was less than 0.3%. They also found a total of 5 clinical parameters in addition to Left ventricular ejection fraction (LVEF) that can predict out-of-hospital cardiac arrest (OHCA) and non-OHCA death.
The risk of sudden cardiac death (SCD) is high early after myocardial infarction (MI). During the last decades, medical treatment has evolved, rates of in-hospital revascularization have increased, and the outcome has improved following MI. Yet, current knowledge and guidelines regarding SCD early after MI largely rely on trials and registry studies conducted in the 1990s and early 2000s. For this purpose, researchers of Sweden conducted a retrospective study to assess the incidence of out-of-hospital cardiac arrest (OHCA) within 90 days after MI in a contemporary setting restricted to patients without a prior ICD who had undergone in-hospital coronary angiography. They also assessed the patient characteristics beyond LVEF as possible predictors of OHCA.
Researchers used data from SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based care in Heart Disease Evaluated According to Recommended Therapies) and additional data from the Swedish Cardiopulmonary Resuscitation Registry, and the Swedish Pacemaker and Implantable Cardioverter-Defibrillator (ICD) Registry. A total of 121,379 cases of MI, who had undergone coronary angiography and were discharged alive between 2009 to 2017 without a prior ICD, were followed up to 90 days. Researchers used Cox regression models to assess the associations between clinical parameters and out-of-hospital cardiac arrest (OHCA).
