Coronary artery diseasePrediction of One-Year Mortality Among 30-Day Survivors After Primary Percutaneous Coronary Interventions
Section snippets
Patient population
For the purpose of this analysis, we pooled clinical, demographic, angiographic, in-hospital clinical events, and outcome data of patients with ST-elevation myocardial infarction (STEMI) who underwent primary PCI and were enrolled in the Stent-PAMI and the CADILLAC trials (training set).1, 2 The rationale, methods, and results of these patient studies have been previously published.1, 2 Briefly, the Stent-PAMI trial evaluated the efficacy of stent versus conventional balloon angioplasty in
Univariate association of 1-year mortality among 30-day survivors
Of the 3,280 patients in PAMI and CADILLAC who survived >30 days after the initial hospitalization, 74 (2.3%) died at the end of 1 year. Thirty-three percent of these deaths occurred in the first 3 months. Table 1, Table 2, Table 3 present differences in baseline clinical characteristics, angiographic features, and in-hospital treatments and treatments between patients who died and those who survived. Univariate correlates significantly associated with death (p <0.05) at 1 year among 30-day
Discussion
Our study is the first to provide an insight into the factors that are associated with death at 1 year among patients who undergo primary PCI and survive >30 days. Although some of the information that was available at presentation maintained its predictive value for later death, other data that were available after admission during hospitalization provided additional prognostic information. The finding of older age and lower body weight as a predictor of 30-day to 1-year mortality is

Prognostic Role of Left Ventricular Dysfunction in Patients With Coronary Artery Disease After an Ambulatory Cardiac Rehabilitation Program
2019, American Journal of CardiologyEarly Ventricular Tachycardia or Fibrillation in Patients With ST Elevation Myocardial Infarction Undergoing Primary Percutaneous Coronary Intervention and Impact on Mortality and Stent Thrombosis (from the Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction Trial)
2017, American Journal of CardiologyCitation Excerpt :In contrast, VAs occurring before revascularization are likely related to a large preexisting or actively evolving infarct allowing for initiation of ventricular tachyarrhythmias in the peri-infarct region. Interestingly, the lack of association of late VAs in HORIZONS-AMI is contrary to results from the Pexelizumab in Conjunction With Angioplasty in Acute Myocardial Infarction3 and Primary Angioplasty in Myocardial Infarction (PAMI)17 trials, likely because HORIZONS-AMI enrolled of a more stable patient cohort. The present report represents a post hoc analysis that was not prespecified in the HORIZONS-AMI protocol; however, the stringent enrollment and follow-up process during the trial ensured that errors related to lack of identification of VT/VF before the index procedure and accurate detection of short- and long-term events were minimized.
