Acute coronary syndrome (ACS)-induced posttraumatic stress disorder (PTSD) and clinically significant PTSD symptoms (PTSS) are found in 4 and 12% of patients, respectively. We hypothesized that trauma-focused counseling prevents the incidence of ACS-induced PTSS.
Within 48 h of hospital admission, 190 patients with high distress during ACS were randomized to a single-session intervention of either trauma-focused counseling or an active control intervention targeting the general role of stress in patients with heart disease.

To implement secondary care electronic record linkage for patients hospitalised with suspected or known acute coronary syndrome (ACS) in a complex regional healthcare system and evaluate this e-Registry in terms of patterns of service delivery and 1-year outcomes.
Existing electronic hospital records were linked to create episodes of care using (1) a patient administration system, (2) invasive cardiovascular procedure referrals and (3) a catheter laboratory record. Data were extracted for admissions (1 October 2013 - 30 September 2014) with ICD-10 diagnosis of angina (I200-I209), myocardial infarction (I210-I229), other ischaemic heart disease (I240-I249) or heart failure (I50), linked to other sources to develop a secondary care ACS e-registry and analysed within a Safe Haven.

-Elderly patients are at elevated risk of both ischemic and bleeding complications after an acute coronary syndrome (ACS), and display higher on-clopidogrel platelet reactivity as compared to younger patients. Prasugrel 5 mg provides more predictable platelet inhibition, as compared to clopidogrel, in the elderly, suggesting the possibility of reducing ischemic events without increasing bleeding.-In a multicenter, randomized, open-label, blinded-endpoint trial, we compared a once daily maintenance dose of prasugrel 5 mg with the standard clopidogrel 75 mg in patients >74 years with ACS undergoing percutaneous coronary intervention (PCI).

Smoking cessation is correlated with several psychological, social, biological, and pharmacological aspects. The combined tendency to experience negative emotions and to inhibit the expression of these emotions is indicated as "type D personality," an independent risk marker for clinical outcome in cardiac disease. Despite this effect of type D personality on cardiovascular disease, it is still unclear whether this personality trait may influence smoking cessation after a myocardial infarction.

There are few data on the utility of physician selection of cardiac tests, including no-test, in a chest pain unit (CPU) to rule out acute coronary syndrome in low-risk patients without a history of coronary artery disease. We analyzed consecutive low-risk patients admitted to our CPU between 2012 and 2014 and determined the proportion of patients selected for testing, the type of initial cardiac test selected, and the incidence of major adverse cardiac events (MACEs) at 30 days and 6 months. The study group comprised 619 patients: mean age 57 years (27 to 92), 332 women (54%), and 360 (58%) with multiple cardiac risk factors.

CD34cells expressing KDR (CD34/KDR) represent a small proportion of circulating progenitor cells that have the capacity to interact with platelets and to differentiate into mature endothelial cells, thus contributing to vascular homeostasis and regeneration as well as to re-endothelialization. We investigated the levels of CD34and CD34/KDRprogenitor cells as well as their interaction with platelets in acute coronary syndrome (ACS) patients before the initiation (baseline) of their treatment with a P2Yreceptor antagonist, and at 5-days post-treatment (follow-up). Sixty-seven consecutive ACS patients and thirty healthy subjects (controls) participated in the study.

Investigation of anginal chest pain has traditionally involved either assessment of the coronary anatomy by angiography or noninvasive testing for reversible ischemia. Invasive pressure wire assessment at the time of angiography offers information on both anatomy and physiology. Fractional flow reserve-guided percutaneous coronary intervention is associated with lower resource utilization and improved clinical outcome compared with angiographic guidance alone.

Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor reduces thrombotic events in patients undergoing percutaneous coronary intervention (PCI), but these benefits come at the expense of increased risk of bleeding when compared with aspirin monotherapy. It is unclear whether P2Y12 inhibitor monotherapy might maintain anti-ischemic efficacy while reducing the bleeding risk compared with DAPT after implantation of the current generation of drug-eluting stents (DES).
The SMART-CHOICE trial is a prospective, open-label, multi-center, and randomized study designed to test the non-inferiority of P2Y12 inhibitor monotherapy compared with aspirin plus a P2Y12 inhibitor after mandatory 3-month DAPT in patients undergoing PCI with current-generation DES.

Cardiac troponin (cTn) levels reflect infarct size and depressed left ventricular ejection fraction (LVEF) in patients with non-ST elevation acute coronary syndrome (NSTE-ACS). However, there is very limited information on whether cTn measured with a high-sensitivity (hs) assay would provide incremental prognostic information to the LVEF in NSTE-ACS patients.
This was a registry-based study (SWEDEHEART registry) investigating 20,652 NSTE-ACS patients with available information on hs-cTnT (highest level recorded during the hospitalization) and the LVEF estimated using echocardiography.

Acute coronary syndrome is a common cause of out-of-hospital cardiac arrest (OHCA). In patients with OHCA presenting with ST elevation, immediate coronary angiography and potential percutaneous coronary intervention (PCI) after return of spontaneous circulation are recommended. However, the evidence for this invasive strategy in patients without ST elevation is limited.

Coronary artery disease (CAD) remains the major cause of cardiac morbidity and mortality worldwide, despite the advances in treatment with coronary revascularization and modern antiremodeling therapy. Risk stratification in CAD patients is primarily based on left ventricular volumes, ejection fraction (LVEF), risk scores, and the presence and extent of late gadolinium enhancement (LGE). The prognostic role of T1 mapping in noninfarcted myocardium in CAD patients has not yet been determined.

Recent studies have shown that the thromboxaneA-dependent pathway is dependent upon the adenosine diphosphate (ADP)-P2Y pathway and that strong P2Yreceptor blockade alone causes inhibition of platelet aggregation that is minimally enhanced by aspirin. Data from the PLATO trial suggested that among ticagrelor-treated patients, high compared with low dose (<100mg\day) aspirin is associated with increased risk for ischemic events.
In the current prospective, randomized, placebo-controlled, double-blind, cross-over study, we sought to evaluate the impact of aspirin withdrawal on platelet reactivity in acute coronary syndrome (ACS) patients treated with a potent P2Yblocker.
