ABSTRACT

Objective:To investigate the characteristics of short-term prognostic factors in very elderly patients with acute coronary syndrome (ACS).Methods:A total of 2 912 ACS patients admitted to Shengjing Hospital of China Medical University from January 1, 2010 to October 31, 2014 and treated with percutaneous coronary intervention (PCI) were enrolled and divided into two groups according to age: very elderly group (≥75 years, 480 cases) and control group (< 75 years, 2 432 cases). The clinical data and coronary artery lesions of the included patients were detected. Major cardiovascular adverse events (MACE) occurred within 30 d after discharge were followed up and recorded. The short-term prognostic factors in very elderly patients with ACS were analyzed by Logistic regression.Results:Compared with control group, the percentage of hypertension, global registry of acute coronary events (GRACE) score, high density lipoprotein cholesterol, N-terminal pro-brain natriuretic peptide, the left main lesion ratio and Gensini score in very elderly group were higher, while the percentage of men, number of smoking, hyperlipidemia proportion, red blood cell count, white blood cell count, blood platelet count, albumin, and long term oral administration of aspirin, clopidogrel, statins, angiotensin receptor inhibitor after discharge were lower, and the differences were statistically significant ( P<0.01 or<0.05). During the follow-up period, the all-cause mortality in very elderly group was higher than that in control group: 2.5%(12/480) vs. 0.9% (21/2 432), and the difference was statistically significant ( P<0.01). Multivariate analysis showed that oral angiotensin converting enzyme inhibitor was a protective factor for elderly ACS patients after discharge ( OR = 0.046, 95% CI 0.006 to 0.383, P = 0.004). The receiver operating characteristic curve analysis showed that Gensini score ≥ 87.75 scores was a threshold value for all-cause mortality. The all-cause mortality ratio in high Gensini score (≥ 87.75 scores) group was higher than that in low Gensini score (<87.75 scores) group: 6.6% (9/137) vs. 0.9% (3/343), and the difference was statistically significant ( P<0.01). Conclusions:Very elderly patients with ACS have their own characteristics from both clinical history and prognostic factors. Patients with Gensini score of ≥ 87.75 scores should be closely observed, and drug treatment during hospitalization should be intensified if necessary. Follow-up should be strengthened for such patients, and oral drug treatment should be continued after discharge.

ABSTRACT

Objective:To investigate the prognostic value of infarct size (IS) in patients with acute ST-segment elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (PCI).Methods:A total of 104 patients with acute STEMI who underwent primary PCI treatment in Shengjing Hospital of China Medical University from February 2017 to November 2018 were included in the present study. All patients underwent cardiovascular magnetic resonance (CMR) within one week after primary PCI treatment. The subjects were followed up for two years. Major adverse cardiac events (MACE) included new onset congestive heart failure and/or recurrent nonfatal myocardial infarction and/orcardiac death. The optimal IS cutoff value for MACE was determined by receiver operating character (ROC) curve. Based on the IS cutoff value, the patients were divided into the high IS group and the low IS group. Clinical characteristics between the two groups were compared. A cox regression model was used to analyze the prognostic value of IS in acute STEMI patients treated with primary PCI for the adverse events.Results:The IS cutoff value determined by ROC curve was 13.55%. 50 patients were in the high IS group (IS≥13.55%) and 54 patients were in the low IS group (IS<13.55%). More female patients [14 cases (28.0%) vs. 6 cases (11.1%)] were in the IS group, and a higher proportion of patients in the high IS group had anterior myocardial infarction [27 cases (54.0%) vs. 16 cases (29.6%)] or microvascular obstruction [32 cases (64.0%) vs. 16 cases (29.6%)]. White blood cell counts [11.25(8.90, 13.38) ×10 9/L vs. 9.25(7.58, 11.00) ×10 9/L], troponin I levels [50.63(16.56, 76.30)μg/L vs. 16.58(2.66, 38.42)μg/L] and brain natriuretic peptide levels [178.10(79.70, 281.95)μg/L vs. 79.60(42.83, 183.90)μg/L] in the high IS group were higher than those in the low IS group ( P<0.05), and left ventricular ejection fraction [(45.15±10.65)% vs. (51.95±12.91)%] in the high IS group was lower than that in the low IS group ( P<0.05). Multivariate Cox regression analyses showed that IS was independently associated with the risk of cardiac death in patients with acute STEMI two years after primary PCI( P=0.033, HR=1.075, 95% CI1.006-1.148). Every 1% increase in IS was associated with a 7.5% increase in cardiac death. Conclusions:Infarct size, measured by CMR within one week after primary PCI, is strongly associated with cardiac death in patients with acute STEMI two years after primary PCI. IS could be used as an index for the prognosis of patients with acute STEMI.
