Coronary computed tomography angiography (CCTA) can provide abundant information about the anatomy of the coronary artery. However, this modality is limited in evaluation of myocardial function. Four-dimensional speckle tracking echocardiography (4DSTE) is a novel and sensitive technique for quantitative evaluation of myocardial deformation. We estimated the value of these imaging modalities to predict the risk of MACE in 209 patients with suspected coronary artery disease(CAD) after a median follow-up of 727 days...

Human natural killer (NK) cells play a critical role in the control of viral infections and malignancy. Their importance in human health and disease is illustrated by severe viral infections in patients with primary immunodeficiencies that affect NK cell function and/or development. The recent identification of patients with phosphoinositide-3-kinase (PI3K)-signaling pathway mutations that can cause primary immunodeficiency provides valuable insight into the role that PI3K signaling plays in human NK cell maturation and lytic function...

Increased mean platelet volume (MPV) has been associated with adverse clinical outcomes in patients with ST-segment elevation myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). We aim to assess whether MPV/platelet count (MPV/PC) ratio is a useful marker to predict long-term prognosis in patients with STEMI undergoing PCI. Moreover, the prognostic accuracy of MPV/PC ratio is compared with MPV. 962 consecutive patients with STEMI treated with P-PCI were considered. According to the admission MPV/PC values, the population was divided into two groups: high MPV/PC group (n = 320, MPV/PC ≥ 0...

BACKGROUND: Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCAs) is an increasingly recognized entity. No previous study has evaluated predictors for new major adverse cardiacvascular events (MACEs) and death in patients with MINOCA. METHODS: We conducted an observational study of MINOCA patients recorded between July 2003 and June 2013 and followed until December 2013 for outcome events. Out of 199,163 MI admissions, 9092 consecutive unique patients with MINOCA were identified...

We aimed to evaluate the impact of incomplete revascularization (ICR) on long-term outcomes of patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI). Consecutive patients undergoing CTO PCI at 4 centers were included. Baseline SYNTAX score (bSS: low [≤ 22], intermediate [>22 and <33], high [≥33]), residual SYNTAX score (rSS: 0, >0 and ≤8, >8), and SYNTAX revascularization index (SRI: 100 × (bSS-rSS)/bSS: 100%, 50% to 99%, <50%) were calculated. The primary end point was major adverse cardiac events (MACEs; cardiac death, any myocardial infarction, any revascularization) on follow-up...

We hypothesized that area of calcified aortic valve (ACAV) measured by 2D echocardiography (2DE) can predict future cardiovascular events in asymptomatic severe aortic stenosis (AS).Multidetector computed tomography determined aortic valve calcification load is strongly associated with AS severity but has risks for radiation exposure. Quantification of ACAV by transthoracic 2DE is simple and convenient but its clinical utility has not been extensively studied.We measured ACAV in 124 asymptomatic severe AS patients (80 ± 9 years, 45 males) with preserved left ventricular ejection fraction...

BACKGROUND: The optimal therapeutic strategy for ST-segment elevation myocardial infarction (STEMI) patients found to have multi-vessel disease (MVD) is controversial but recent data support complete revascularisation (CR). Whether CR should be completed during the index admission or during a second staged admission remains unclear. Our main objective was to measure rates of major adverse cardiovascular events (MACEs) during the waiting period in STEMI patients selected for staged revascularisation (SR), in order to determine the safety of delaying CR...

To determine the impact of CYP2C19 genotyping on the occurrence of major adverse cardiovascular events (MACE), in cohort of Iraqi patients on clopidogrel post percutaneous coronary intervention (PCI), a total of 201 Iraqi patients undergoing the latter procedure were enrolled. All enrollees had their CYP2C19 genotyped using PCR and reverse hybridization. Genotyping revealed that CYP2C19 *1, *17, *2 and *8 allele frequencies were respectively 0.604, 0.276, 0.117 and 0.0026. After the exclusion of those with two loss of function alleles, 186 patients were available for follow-up as long as they were on clopidogrel, or until MACE occurred, which was encountered in 8...

BACKGROUND: In general, women have lower risk for cardiovascular disease. We tested whether this sex-specific protection persists also in the presence of hypertensive left ventricular hypertrophy (LVH). METHODS: 12,329 women and men with hypertension and free from prevalent cardiovascular disease enrolled in the prospective Campania Salute Network registry were followed over a median of 4.1years. Subjects were grouped according to the absence or the presence of LVH identified by echocardiography using validated sex-specific cut-off values of LV mass index (>47g/m2...
