K M Eggers, T Jernberg, B Lindahl
INTRODUCTION: There is an expectation that with the adoption of more sensitive cardiac troponin (cTn) assays, unstable angina would become a rarity. However, recent data from the SWEDEHEART registry demonstrated that 15% of patients admitted with non ST-elevation acute coronary syndrome (NSTE-ACS) still were regarded having unstable angina. We aimed to further investigate the clinical characteristics and outcome of these patients. METHODS: Retrospective registry-based analysis (SWEDEHEART) including 3204 unstable patients, 18,194 non ST-elevation myocardial infarction (NSTEMI) patients and 977 controls without acute cardiovascular disease...

OBJECTIVE: Assess the economic burden of cardiovascular events in Medicare beneficiaries with type 2 diabetes mellitus (T2DM). METHODS: This claims-based actuarial analysis queried 2013 and 2014 Medicare 5% Samples, defining a denominator of fee-for-service beneficiaries. Average per patient per month allowed cost ($PPPM) was calculated for T2DM, demographically adjusted non-T2DM, and denominator. Per member per month allowed cost ($PMPM) was calculated by dividing total population cost by member months in the denominator...

BACKGROUND: With the rising incidence as well as the medical expenditure among patients with unstable angina pectoris, the research aimed to investigate the inpatient medical expenditure through the combination of diagnosis-related groups (DRGs) among patients with unstable angina pectoris in a Grade A tertiary hospital to conduct the referential standards of medical costs for the diagnosis. METHODS: Single-factor analysis and multiple linear stepwise regression method were used to investigate 3933 cases between 2014 and 2016 in Beijing Hospital (China) whose main diagnosis was defined as unstable angina pectoris to determine the main factors influencing the inpatient medical expenditure, and decision tree method was adopted to establish the model of DRGs grouping combinations...

Background The aim of the study was to assess the value of post-operative cardiac troponin T-levels, measured with a new highly sensitive assay (hs-cTnT), as a suitable parameter to predict patients' outcome after cardiac surgery. With the introduction of the new hs-cTnT assay the correlation between measured levels and the post-operative patient's outcome remains to be evaluated. Methods Patients undergoing coronary artery bypass grafting (n = 213) were included. Perioperative measurements of hs-cTnT and CK-MB were correlated to parameters of clinical outcome and further explored...

AIM: To compare in patients with ACS (acute coronary syndromes) a PCI (percutaneous coronary intervention) approach based on FFR (fractional flow reserve) vs. one based on OCT (optical coherence tomography). METHODS AND RESULTS: Consecutive patients admitted for ACS and treated with a PCI approach based on OCT or on FFR (recruited in two different studies) were compared and matched with propensity score analysis. Target Lesion revascularization (TLR) was the primary end point, while major adverse cardiovascular events [MACEs defined as the composite of death from cardiac causes, non-fatal MI, clinically driven target vessel revascularization (TVR), or re-hospitalization due to unstable angina] were the secondary ones...

BACKGROUND: XuefuZhuyu decoction (XFZY) is a well-known traditional Chinese herbal medicine for the treatment of various cardiovascular diseases, such as unstable angina pectoris and myocardial ischemia-reperfusion injury. However, the mechanism by which XFZY contributes to the amelioration of cardiac injury remains unclear. METHODS: H9C2 cells were cultured under the hypoxic condition for 10 h and reoxygenated for 2 h. In the presence of various concentrations of XFZY for 12 h, the cell viability was measured by MTT assay...

Although statistical evidence is clear regarding the dangerousness of unstable angina (UA), a form of coronary heart disease (CHD) characterised by high mortality and morbidity globally, it is important to recognise that diagnostic precision for the condition is unfavourable. In the present research, to gain insight into candidate biomarkers, the author draws on (1)H NMR-based serum metabolic profiling to analyze the unstable angina pectoris (UAP) metabolic signatures; this constitutes an effective way to produce medical diagnosis...

BACKGROUND: Wellens syndrome is a pattern of electrocardiographic (ECG) changes in the context of unstable angina characterized with deep inverted T-waves or biphasic T-waves in the precordial leads. These specific ECG changes are highly suggestive of stenosis in the left anterior descending artery (LAD), which can result in acute myocardial infarction, left ventricular dysfunction, or death. Human immunodeficiency virus (HIV) infection is known as an independent risk factor for the cardiovascular disease...

We appreciate the insights and concerns raised in the above letter to the editor. The authors have thoughtfully highlighted some important distinctions between the original derivation of NOTR and our validation study.(1,2) Specifically, the original NOTR derivation included cardiac death, acute myocardial infarction (MI), unstable angina (UA), and "urgent and emergent" revascularization in a composite safety endpoint (and did not include "elective" coronary revascularizations). Our study included death, MI, and any coronary revascularization events, but did not include UA...

Smoking is an important risk factor for cardiovascular disease (CVD) morbidity and mortality. The impact of statin therapy on CVD risk by smoking status has not been fully investigated. Therefore we assessed the impact of statin therapy on CVD outcomes by smoking status through a systematic review of the literature and meta-analysis of available randomized controlled trials (RCTs). The literature search included EMBASE, ProQuest, CINAHL and PUBMED databases to 30 January 2016 to identify RCTs that investigated the effect of statin therapy on cumulative incidence of major CVD endpoints (e...

Patients with an acute coronary syndrome (ACS) due to plaque rupture had a worse prognosis when compared with those without plaque rupture with a higher rate of target vessel revascularization and readmission for unstable angina, suggesting that both stent failure and disease progression occur more frequently. However, it is not known whether recurrent episodes of coronary instability in the same patient are caused by the same pathogenetic mechanism. Thus, we sought to investigate the mechanisms of coronary instability imaged by optical coherence tomography in patients with recurrent ACS events...

BACKGROUND AND PURPOSE: Even though current guidelines suggest that noninvasive ventilatory correction (NIVC) could be considered for acute ischemic stroke patients with obstructive sleep apnea, available evidence is conflicting, with no adequately powered randomized clinical trial being available to date. METHODS: We conducted a systematic review and meta-analysis of all available literature data evaluating the effect of NIVC on neurological improvement (based on decrease in National Institutes of Health Stroke Scale score), vascular events (recurrent stroke, transient ischemic attack, myocardial infarction and unstable angina), and mortality during the follow-up period...

Hypothetically, diminished platelet reactivity (PR) during dual antiplatelet therapy (DAPT) should cause extra major bleeding events (MBE), although definite evidence is lacking. Multiple scores have been proposed to stratify bleeding risk, but their predictive value during DAPT is unclear. We compared the performance of the Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE) with PR testing to predict MBE in Korean patients with acute coronary syndrome...

BACKGROUND: Revascularization therapy relieves myocardial ischemia, but can also result in ischemia-reperfusion injury caused by oxidative stress. However, the biokinetics of oxidative stress after myocardial ischemia-reperfusion are uncertain. This study aimed to evaluate the dynamics of oxidative stress after off-pump coronary artery bypass grafting (OPCAB) by measuring urinary biopyrrin levels. Biopyrrin is an oxidative metabolite of bilirubin thought to reflect oxidative stress, along with reactive nitrogen species (RNS)...
