ABSTRACT

BACKGROUND: It remains controversial whether a cancer history increases the risk of cardiovascular (CV) events among patients with myocardial infarction (MI) who undergo revascularization.Methods and Results: Patients who were confirmed as type 1 acute MI (AMI) by coronary angiography were retrospectively analyzed. Patients who died in hospital or those not undergoing revascularization were excluded. Patients with a cancer history were compared with those without it. A cancer history was examined in the in-hospital cancer registry. The primary outcome was a composite of cardiac death, recurrent type 1 MI, post-discharge coronary revascularization, heart failure hospitalization, and stroke. Among 551 AMI patients, 55 had a cancer history (cancer group) and 496 did not (non-cancer group). Cox proportional hazards model revealed that the risk of composite endpoint was significantly higher in the cancer group than in the non-cancer group (adjusted hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.13-2.82). Among the cancer group, patients who were diagnosed as AMI within 6 months after the cancer diagnosis had a higher risk of the composite endpoint than those who were diagnosed as AMI 6 months or later after the cancer diagnosis (adjusted HR: 5.43; 95% CI: 1.55-19.07). CONCLUSIONS: A cancer history increased the risk of CV events after discharge among AMI patients after revascularization.

ABSTRACT

Objective Although blood thrombogenicity seems to be one of the determinant factors for the development of acute myocardial infarction (MI), it has not been dealt with in-depth. This study aimed to investigate blood thrombogenicity and its change in acute MI patients. Methods and Results We designed a prospective, observational study that included 51 acute MI patients and 83 stable coronary artery disease (CAD) patients who underwent cardiac catheterization, comparing thrombogenicity of the whole blood between: (1) acute MI patients and stable CAD patients; and (2) acute and chronic phase in MI patients. Blood thrombogenicity was evaluated by the Total Thrombus-Formation Analysis System (T-TAS) using the area under the flow pressure curve (AUC 30 ) for the AR-chip. Acute MI patients had significantly higher AUC 30 than stable CAD patients (median [interquartile range], 1,771 [1,585-1,884] vs. 1,677 [1,527-1,756], p = 0.010). Multivariate regression analysis identified acute MI with initial TIMI flow grade 0/1 as an independent determinant of high AUC 30 ( ß = 0.211, p = 0.013). In acute MI patients, AUC 30 decreased significantly from acute to chronic phase (1,859 [1,550-2,008] to 1,521 [1,328-1,745], p = 0.001). Conclusion Blood thrombogenicity was significantly higher in acute MI patients than in stable CAD patients. Acute MI with initial TIMI flow grade 0/1 was significantly associated with high blood thrombogenicity by multivariate analysis. In acute MI patients, blood thrombogenicity was temporarily higher in acute phase than in chronic phase.

ABSTRACT

BACKGROUND: Sudden cardiac arrest is a serious complication of acute myocardial infarction (MI). Although in-hospital mortality from MI has decreased, the mortality of MI patients complicated with out-of-hospital cardiac arrest (OHCA) remains high. However, the features of acute MI patients with OHCA have not been well known. OBJECTIVES: We sought to characterize the clinical and angiographic features of acute MI patients with OHCA comparing with those without OHCA. METHODS: We retrospectively analyzed 480 consecutive patients with acute MI undergoing percutaneous coronary intervention. Patients complicated with OHCA were compared with patients without OHCA. RESULTS: Of the patients, 141 (29%) were complicated with OHCA. Multivariate analysis revealed that age (odds ratio [OR]: 0.8; 95% confidence interval [CI]: 0.7 to 0.9 per 5 years; p < 0.001), estimated glomerular filtration rate (OR: 0.8; 95% CI: 0.7 to 0.8 per 10 ml/min/1.73 m2; p < 0.001), peak creatine kinase-myocardial band (OR: 1.3; 95% CI: 1.2 to 1.4 per 102 U/l; p < 0.001), calcium-channel antagonists use (OR: 0.4; 95% CI: 0.2 to 0.7; p = 0.002), the culprit lesion at the left main coronary artery (OR: 5.3; 95% CI: 1.9 to 15.1; p = 0.002), and the presence of chronic total occlusion (OR: 2.9; 95% CI: 1.5 to 5.7; p = 0.001) were significantly associated with OHCA. CONCLUSIONS: Younger age, no use of calcium-channel antagonists, worse renal function, larger infarct size, culprit lesion in the left main coronary artery, and having chronic total occlusion were associated with OHCA.
