BACKGROUND: While patients presenting to emergency departments (ER) with chest pain are increasingly managed in chest pain units (CPU) that utilize accelerated diagnostic protocols for risk stratification, such as single-photon emission computed tomography (SPECT) myocardial perfusion imaging (MPI), data are lacking regarding the prognostic implications of mildly abnormal scans in this population. OBJECTIVES: To evaluate the prognostic implications of mildly abnormal SPECT MPI results in patients with acute chest pain...

BACKGROUND: Trials have shown superiority of primary percutaneous intervention (PPCI) over in-hospital thrombolysis in ST-elevation myocardial infarction (STEMI) patients treated within 6-12 hours from symptom onset. These studies also included high-risk patients not all of whom underwent a therapeutic intervention. OBJECTIVES: To compare the outcome of early-arriving stable STEMI patients treated by thrombolysis with or without coronary angiography to the outcome of PPCI-treated STEMI patients...

We investigated the independent and combined association of resting heart rate (RHR expressed as beats/min, bpm) and body mass index (BMI) with SYNTAX score (SS) in patients with stable angina. We divided 312 patients into 4 groups according to RHR quartiles: Q1 (<65 bpm), Q2 (65-69 bpm), Q3 (70-79 bpm), and Q4 (≥80 bpm). The SS (12.0 ± 9.0, 16.0 ± 15.5, 18.0 ± 16.5, and 20.0 ± 27.5; P < .001) was significantly higher for those in Q4 than for those in Q1, Q2, and Q3. Multivariate logistic regression analysis indicated that each 10-bpm increment in RHR was significantly associated with SS (odds ratio [OR] 1...

Kai M Eggers, Bertil Lindahl
BACKGROUND: The use of sex-specific cutoffs for cardiac troponin (cTn) is currently debated. Although endorsed by scientific working groups, concerns have been raised that sex-specific cutoffs may have only a small clinical effect at the cost of increased complexity in decision-making. METHODS: We reviewed studies investigating the interrelations between high-sensitivity (hs) cTn results and sex, diagnoses, and outcome. Investigated populations included community-dwelling subjects and patients with stable angina, congestive heart failure, or acute chest pain including those with acute coronary syndromes...

BACKGROUND: Some aspects of prognosis are not reflected by cumulative survival estimates. These aspects include information on the time already survived by the patient and the patient's survival compared with the general population. Conditional survival (ie, conditional on having survived a certain period of time already) and relative conditional survival (ie, compared with the general population) do incorporate these aspects. We investigated these measures of prognosis in patients undergoing percutaneous coronary intervention...

BACKGROUND: Blood lipid management is one of the effective strategies for coronary heart disease, and statins are the first-line lipid-lowering drugs. Low density lipoprotein cholesterol (LDL-C) drop brings about cardioprotective effects. Proprotein convertase subtilisin kexin type 9 (PCSK9) is known to increase LDL-C, thus hazarding LDL-C reduction-induced benefits. To date, how PCSK9 responds to various lipid-lowering strategies has not been fully clarified. METHODS: This study involves patients with stable angina and aims to explore and clarify the short-term impacts of rosuvastatin and ezetimibe, alone or in combination, on circulating PCSK9...

BACKGROUND: Fractional flow reserve (FFR) is not firmly established as a guide to treatment in patients with acute coronary syndromes (ACS). Primary goals were to evaluate the impact of integrating FFR on management decisions and on clinical outcome of patients with ACS undergoing coronary angiography, as compared with patients with stable coronary artery disease. METHODS AND RESULTS: R3F (French FFR Registry) and POST-IT (Portuguese Study on the Evaluation of FFR-Guided Treatment of Coronary Disease), sharing a common design, were pooled as PRIME-FFR (Insights From the POST-IT and R3F Integrated Multicenter Registries - Implementation of FFR in Routine Practice)...

BACKGROUND: The American College of Cardiology (ACC) Appropriate Use Criteria (AUC) for radionuclide myocardial perfusion scans (MPS) was developed to promote its rational use in the assessment of stable ischaemic heart disease (IHD). We sought to validate the applicability of this document in the Australian context. METHODS: 1009 consecutive patients who underwent MPS were retrospectively audited at a single major metropolitan hospital in Victoria, Australia. Appropriateness was assigned based on the 2013 ACC AUC, and common indications and predictors of positive scan results were examined...

BACKGROUND: A recent study showed that coronary high-intensity plaques (HIPs) visualized by noncontrast T1-weighted imaging (T1WI) in cardiac magnetic resonance were associated with coronary events. We used coronary angioscopy to analyze HIP plaque morphology. METHODS AND RESULTS: A total 17 lesions from 17 patients with stable or unstable angina pectoris were evaluated at the culprit lesion by noncontrast T1WI using 1.5-T magnetic resonance; of them, nine (53%) were HIPs and eight (47%) were non-HIPs, and all were analyzed by coronary angioscopy...

Fractional flow reserve (FFR) is a reference invasive diagnostic test to assess the physiological significance of an epicardial coronary artery stenosis. FFR-guided percutaneous coronary intervention in stable coronary artery disease has been assessed in three seminal clinical trials and the indications for FFR assessment are expanding into other clinical scenarios. In this article we review the theoretical, experimental and clinical basis for FFR measurement. We place FFR measurement in the context of the comprehensive invasive assessment of coronary physiology in patients presenting with known or suspected angina pectoris in daily clinical practice, and review the recent developments in FFR assessment...

AIMS: The diagnosis of stable angina involves the use of probability estimates based on clinical presentation, age, gender and cardiovascular risk factors. In view of the link between the cardiac and systemic vasculature we tested whether non-invasive measures of systemic micro- and macrovascular structure and function differentiate between individuals with flow-limiting coronary artery disease (CAD) and those with normal coronary arteries (NCA). METHODS AND RESULTS: We recruited 84 patients undergoing elective coronary angiography for investigation of symptoms of stable angina...

BACKGROUND AND AIMS: Many coronary artery disease (CAD) patients exhibit chronic low-grade inflammation. Carotenoids are anti-oxidants with potential anti-inflammatory properties. Here, we first assessed relationships between interleukin (IL)-6 and individual carotenoids in plasma from CAD patients. Based on the results, we proceeded to assess anti-inflammatory effects of one carotenoid, lutein, in peripheral blood mononuclear cells (PBMCs) from CAD patients. METHODS: Lutein + zeaxanthin (isomers with lutein being dominant), β-cryptoxanthin, lycopene, α- and β-carotene and IL-6 were measured in plasma from 134 patients with stable angina (SA) and 59 patients with acute coronary syndrome...

Prediction of coronary events remains elusive. Carotid atherosclerosis may be a surrogate for coronary risk, as carotid and coronary diseases occur simultaneously - albeit at times with a weak association - depending on clinical presentation. We investigated carotid and coronary atherosclerosis in men with new-onset unstable coronary artery disease (CAD) presenting with acute ST-segment elevation myocardial infarction (STEMI) vs. long-standing severe chronic stable angina (CSA). Bilateral carotid artery and 3-vessel coronary artery atherosclerosis burdens were measured within 1 month, respectively, by 3D-volumetric carotid magnetic resonance imaging and coronary angiography-derived modified CASS-50 score...
