INTRODUCTION: Near-infrared spectroscopy (NIRS) is a new method to identify lipid core plaque (LCP). The LCP and vascular response were assessed with NIRS to examine whether LCP was compressed or redistributed during percutaneous coronary intervention with stent implantation. METHODS: In 25 patients with non-ST segment elevation myocardial infarction (NSTEMI) NIRS acquisition was performed after predilation, stent implantation with nominal pressure and high-pressure post-dilation with a non-compliant balloon...

BACKGROUND: Erythropoietin (EPO) has been suggested to promote cardiac repair after MI. However, the randomized, double-blind, placebo controlled REVIVAL-3 trial showed that short term high dose EPO in timely reperfused myocardium does not improve left ventricular ejection fraction after 6 months. Moreover, the study raised safety concerns due to a trend towards a higher incidence of adverse clinical events as well as a increase in neointima formation after treatment with EPO. The present study therefore aimed to assess the 5-year clinical outcomes...

BACKGROUND: Women hospitalized with a non-ST segment elevation acute coronary syndrome (ACS) have worse clinical outcomes compared with men. An early invasive strategy with prompt coronary revascularization may mitigate sex differences in outcomes. However, few contemporary studies have evaluated whether clinical outcomes differ between women and men presenting with ACS treated with an early invasive strategy. METHODS AND RESULTS: A population-based cohort of hospitalized ACS patients who received prompt cardiac catheterization from 2008 to 2011 in Ontario, Canada and followed for up to 2 years was studied...

AIMS: The clinical definition and optimal treatment for myocardial infarction (MI) type 2 (T2MI) are not well established. We assessed differences in presentation, treatment and outcomes of patients with MI type 1 (T1MI) and T2MI. METHODS: The data of MI patients enrolled in the AMIS Plus cohort with T2MI were compared with T1MI using propensity score matching. RESULTS: A total of 13 829 patients had T1MI and 1091 (7.3%) T2MI. Patients with T2MI were older, often female, with more risk factors and comorbidities, and less ST segment elevation...

BACKGROUND: The GRACE (Global Registry of Acute Coronary Events) risk score is recommended for risk stratification in acute coronary syndrome (ACS). It does not include sex, a variable strongly associated with ACS prognosis. The aim of this study was to examine if sex adds prognostic information to the GRACE score in a contemporary population. MATERIALS AND METHODS: Analysis of discrimination and calibration of GRACE score in the validation population, derived from the ARIAM-SEMICYUC registry (2012-2015)...

Bivalirudin is a direct thrombin inhibitor used during percutaneous coronary intervention (PCI). Treatment with bivalirudin compared to heparin plus glycoprotein IIb/IIIa inhibitors (GPI) reduced bleeding complications, but resulted in higher rates of ischemic events, including acute stent thrombosis in ST segment elevation myocardial infarction (STEMI) patients. Thus, it may be considered a reasonable alternative antithrombotic agent in patients at high risk of bleeding undergoing PCI. However its superiority over heparin alone is questioned particularly in the era of novel antiplatelet agents and transradial PCI...

The aim of the present study was to investigate whether the serum levels of complements and high-sensitivity C-reactive protein (hs-CRP) in patients with acute myocardial infarction (AMI) are associated with the severity of myocardial injury. Consecutive patients (n=110) with AMI and 33 healthy individuals, who served as control subjects, were enrolled from May 2013 to February 2015. These patients were divided into two groups, those with ST segment elevation MI (STEMI) and those with non-ST segment elevation MI (NSTEMI)...

The present study aimed to compare the effect of conservative pharmacotherapy (CP) and staged percutaneous coronary intervention (SPCI) on significant non-culprit vessels in patients with ST-segment elevation myocardial infarction (STEMI). A total of 266 male and 40 female patients were divided into two groups following their first successful PCI treatment: i) Patients in the complete revascularization (CR) group undergoing SPCI; and ii) patients in the CP group undergoing CP. Follow-up data were collected at 180 or 360 days after surgery to compare the rates of major adverse cardiovascular events (MACE), recurrent myocardial infarction, recurrent angina pectoris and MACE-free survival rates between the two groups...

Vascular inflammation and associated ongoing inflammatory responses are considered as the critical culprits in the pathogenesis of acute atherothrombotic events such as acute coronary syndrome (ACS) and myocardial infarction (MI). ST segment elevation myocardial infarction (STEMI) is considered as one of the prominent clinical forms of ACS. Moreover, C-reactive protein (CRP) is an important acute phase prsotein, which may be estimated using high-sensitivity methods (hs-CRP), and its elevated level in body fluids reflects chronic inflammatory status...

Multiple variations exist in performing a primary percutaneous coronary intervention (pPCI) in ST-segment elevation myocardial infarction (STEMI) among various cardiologists. These variations range from the choice of peripheral access artery (radial vs femoral), performance or time of complete angiography including left ventriculography, and nonculprit vessel angiography before or after intervening on the culprit vessel. The reasons for such variations include emphasis on door-to-balloon time, knowledge of cardiac anatomy before proceeding with pPCI, physician expertise, and the level of comfort with radial approach...

AIMS: Adiponectin, an adipocyte-specific secretory protein, abundantly exists in the blood stream while its concentration paradoxically decreases in obesity. Hypoadiponectinemia is one of risks of cardiovascular diseases. However, impact of serum adiponectin concentration on acute ischemic myocardial damages has not been fully clarified. The present study investigated the association of serum adiponectin and creatine kinase (CK)-MB levels in subjects with ST-segment elevation myocardial infarction (STEMI)...

BACKGROUND: Left ventricular ejection fraction (LVEF) and infarct size (ISZ) are key predictors of long-term survival after myocardial infarction (MI). However, little is known about the biochemical pathways driving LV dysfunction after MI. To identify novel biomarkers predicting post-MI LVEF and ISZ, we performed metabolic profiling in the GIPS-III randomized clinical trial (Glycometabolic Intervention as Adjunct to Primary Percutaneous Intervention in ST Elevation Myocardial Infarction)...

Objective: To investigate the effect of intracoronary administration of nicorandil prior to primary percutaneous coronary intervention (PPCI) on myocardial perfusion and short-term clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 158 patients with STEMI undergoing PPCI from January 2014 to December 2015 in Fuzhou General Hospital were enrolled consecutively in this prospective controlled randomized trial. Patients were assigned into three groups with random number table: the nicorandil group (patients received intracoronary administration of 6 mg nicorandil after guide wire or balloon successfully crossed the target lesion, n=53), the nitroglycerin group (patients received intracoronary administration of 300 μg nitroglycerin after after guide wire or balloon successfully crossed the target lesion, n=52) and the control group(patients received routine treatment, n=53)...

Importance: Renal transplantation is associated with reduction in the risk for myocardial infarction (MI) in patients with chronic kidney disease requiring long-term dialysis (stage 5D CKD). Whether outcomes of MI differ among renal transplant recipients vs patients with stage 5D CKD or those without CKD has not been well examined. Objectives: To compare in-hospital reperfusion rates and outcomes of ST-segment elevation MI (STEMI) in renal transplant recipients vs the stage 5D CKD group or the non-CKD group...

We report on a 69-year-old woman who demonstrated native coronary artery and grafted vessel spasm following on-pump coronary artery bypass grafting (CABG). Despite intraaortic balloon pump (IABP) insertion, electrocardiogram (ECG) abnormalities did not disappear. Emergency coronary angiography (CAG) was performed. The patient was successfully treated with systemic and intracoronary injection of vasodilator agents. ECG changes disappeared, with normalized and stable hemodynamic function. Intraaortic balloon pump was maintained for 48 h...

Effects of daily fluctuation of ambient temperature and concentrations of air pollutants on acute cardiovascular events have not been well studied. From January 2011 to December 2012, a total of 56,863 consecutive ST-segment elevation myocardial infarction (STEMI) patients who underwent primary percutaneous coronary intervention were registered from 929 institutes with median interinstitutional distance of 2.6 km. We constructed generalized linear mixed models in which the presence or absence of patients with STEMI per day per institute was included as a binomial response variable, with daily meteorologic and environmental data obtained from their respective observatories nearest to the institutes (median distance of 9...
