BACKGROUND: Evidence suggests that oxidative stress plays a principal role in myocardial damage following ischemia/reperfusion events. Recent studies have shown that the antioxidant properties of N-acetylcysteine (NAC) may have cardioprotective effects in high doses, but-to the best of our knowledge-few studies have assessed this. OBJECTIVES: Our objective was to investigate the impact of high-dose NAC on ischemia/reperfusion injury. METHODS: We conducted a randomized double-blind placebo-controlled trial in which 100 consecutive patients with ST-elevation myocardial infarction undergoing percutaneous coronary intervention (PCI) were randomly assigned to the case group (high-dose NAC 100 mg/kg bolus followed by intracoronary NAC 480 mg during PCI then intravenous NAC 10 mg/kg for 12 h) or the control group (5% dextrose)...

Safflower Injection is one kind of injections derived from traditional Chinese medicine. It is widely applied to treat cerebrovascular diseases such as acute cerebral infarction, stroke, coronary heart disease, and angiitis. However, most adverse reactions of Safflower Injection in clinic are caused by its quality problems. In this study, 10 batches of normal and 42 batches of abnormal Safflower Injections were obtained from the clinical practice. Their quality fluctuations were detected by chemical fingerprinting (CF, ultra-performance liquid chromatography tandem mass spectrometry) and bioassays including cell-based biological profile (CBP) assay and enzymatic assay...

BACKGROUND: Patients with angina yet having unobstructed coronaries are found in ∼50% of cases undergoing invasive angiography. Coronary spasm and microvascular dysfunction can be responsible for the clinical presentation in ∼60% of cases. However, little is known about structural changes in the myocardium. The aim of this study was to describe findings in endomyocardial biopsies of symptomatic patients with unobstructed coronaries. PATIENTS AND METHODS: We retrospectively analyzed a cohort of 1416 consecutive patients who underwent endomyocardial biopsy sampling and coronary angiography between 2002 and 2016 for various clinical indications...

AIMS: Circulating levels of microRNAs (miRNAs) are emergent promising biomarkers for cardiovascular disease. Altered expression of miRNAs has been related to heart failure (HF) and cardiac remodelling. We measured the concentration gradients across the coronary circulation to assess their usefulness to diagnose HF of different aetiologies. METHODS AND RESULTS: Circulating miRNAs were measured in plasma samples simultaneously obtained from the aorta and the coronary venous sinus in patients with non-ischaemic HF (NICM-HF, n = 23) ischaemic HF (ICM-HF, n = 41), and in control patients (n = 11)...

BACKGROUND: CAD (Coronary Artery Disease) is a complex disease that influenced by various environmental and genetic factors. Previous studies have found many single nucleotide polymorphisms (SNPs) associated with the risk of CAD occurrence. However, the results are inconsistent. In this study, we aim to investigate genetic etiology in Chinese Han population by analysis of 7 SNPs in lipid metabolism pathway that previously has been reported to be associated with CAD. METHODS: A total of 631 samples were used in this study, including 435 CAD cases and 196 normal healthy controls...

Obesity is a well-established risk factor for cardiovascular disease (CVD), but the underweight population of body mass index (BMI) below 18.5 kg/m has not been an object of concern. The objective of this study is to investigate whether underweight could be an independent risk factor for CVD in a population-based cross-sectional study.Cross-sectional data of 2013 Behavioral Risk Factor Surveillance System (BRFSS) database encompassing 491,773 US adult subjects were used to assess risk for CVD. Primary outcomes were the incidence and relative risks (RRs) of CVD including stroke, heart attack/myocardial infarction, or coronary artery disease according to BMI category...

Background -Cardiac rehabilitation is strongly recommended after myocardial infarction (MI), percutaneous coronary intervention (PCI), or coronary artery bypass surgery (CABG), but is historically underused. We sought to evaluate variation in cardiac rehabilitation participation across the United States. Methods -From administrative data from the Veterans Affairs (VA) healthcare system and a 5% Medicare sample, we used ICD-9 codes to identify patients hospitalized for MI, PCI, or CABG from 2007-2011. After excluding patients who died within 30 days of hospitalization, we calculated the percent of patients who participated in one or more outpatient visits for cardiac rehabilitation during the 12 months after hospitalization...

BACKGROUND: Although drug trials with niacin and cholesteryl ester transfer protein inhibitors that substantially increase high-density lipoprotein-cholesterol (HDL-C) failed to reduce the risk of coronary heart disease, HDL protection of the cardiovascular system cannot be easily denied. Hence, it may be HDL subfractions that are responsible for the long-held and consistent cardioprotective association of HDL. Arterial stiffness has been increasingly recognized as a strong predictor of subclinical vascular disease, atherosclerotic disease, and cardiovascular mortality...
