In this study, we evaluated the change in left ventricular end-diastolic pressure (LVEDP) after primary percutaneous coronary intervention (PCI) and its impact on in-hospital outcomes and 30-day and three-month quality of life (SAQ-7), ejection fraction (EF), and major adverse cardiovascular events (MACE). LVEDP ≥19 mmHg was taken as elevated LVEDP. In a sample of 318 patients, 18.9% (n=60) were females and mean age was 55.7 ± 10.52 years. Post-procedure elevated LVEDP was observed in 20.8% (n=66) with a mean reduction of 1.65 ± 4.35 mmHg. LVEDP declined in 39% (n=124) and increased in 10.7% (n=34). In-hospital mortality rate (9.1% vs. 2.4%, p=0.011), 30-day MACE (9.1% vs. 4.0%), and three-month MACE (21.2% vs. 5.6%) were found to be significantly higher among patients with elevated LVEDP, respectively. Elevated LVEDP was found to be associated with a reduced SAQ-7 score (89.84 ± 8.09 vs. 92.29 ± 3.03, p<0.001) and reduced (25–40%) EF (55.6% vs. 22.6%) at three-month follow-up. LVEDP declined acutely in a significant number of patients after primary PCI. Post- procedure elevated LVEDP was found to be associated with poor quality of life and an increased risk of immediate and short-term MACE.
