OBJECTIVES: We sought to study whether the level of completeness of revascularization as measured by the SYNTAX revascularization index (SRI) independently predicts adverse ischemic events after percutaneous coronary intervention (PCI) with second-generation drug-eluting stents (DES). BACKGROUND: The SRI quantifies the proportion of revascularized myocardium. It has been shown to independently predict adverse ischemic events after PCI with first-generation DES. METHODS: Among 1,900 patients enrolled in a registry to evaluate safety and effectiveness of everolimus drug-eluting stent (SEEDS) for coronary revascularization, the SRI was calculated and available for 1,851 patients...

Continuous cardiac afterload evaluation could represent a useful tool during general anesthesia (GA) to titrate vasopressor effect. Using beat to beat descending aortic pressure(P)/flow velocity(U) loop obtained from esophageal Doppler and femoral pressure signals might allow to track afterload changes. Methods We defined three angles characterizing the PU loop (alpha, beta and Global After-Load Angle (GALA)). Augmentation index (AIx) and total arterial compliance (Ctot) were measured via radial tonometry. Peripheral Vascular Resistances (PVR) were also calculated...

BACKGROUND: Women hospitalized with a non-ST segment elevation acute coronary syndrome (ACS) have worse clinical outcomes compared with men. An early invasive strategy with prompt coronary revascularization may mitigate sex differences in outcomes. However, few contemporary studies have evaluated whether clinical outcomes differ between women and men presenting with ACS treated with an early invasive strategy. METHODS AND RESULTS: A population-based cohort of hospitalized ACS patients who received prompt cardiac catheterization from 2008 to 2011 in Ontario, Canada and followed for up to 2 years was studied...

BACKGROUND: Fabry disease is a lysosomal storage disorder with an incidence of 1:1600 for the late-onset IVS4+919G>A cardiac variant mutation in Taiwan. Signs and symptoms of this cardiac variant include left ventricular hypertrophy, mitral insufficiency and/or arrhythmias. The search for biomarkers that might predict the clinical outcomes and guide treatment options is important. We thus investigated relationships between Fabry disease biomarkers (such as globotriaosylceramide (Gb3), globotriaosylsphingosine (lyso-Gb3)/related analogues) and age, gender, enzyme activity, clinical manifestations and severity of the disease in these patients...

OBJECTIVE: Physical complaints such as faintness, dizziness, cold limbs and headaches have been well-established in chronic low blood pressure (hypotension). This study investigated the occurrence of adverse emotional states and the symptoms of depression in this condition. As autonomic dysregulation, particularly diminished sympathetic tone, is believed to be involved in the etiology of hypotension, the impact of different facets of autonomic cardiovascular control on mood and depressive symptoms was also explored...

Surgical site infection (SSI) is a major infectious complication that increases mortality, morbidity, and healthcare costs. There are scores attempting to classify patients for calculating SSI risk. Our objectives were to validate the Australian Clinical Risk Index (ACRI) in a European population after cardiac surgery, comparing it against the National Nosocomial Infections Surveillance-derived risk index (NNIS) and analyzing the predictive power of ACRI for SSI in valvular patients. All the patients that who underwent cardiac surgery in a tertiary university hospital between 2011 and 2015 were analyzed...

BACKGROUND: Cardiovascular risk in type 1 diabetes mellitus (T1DM) is associated with endothelial dysfunction, inflammation, and altered immunity. CD4(+) CD28(null) T-cells are a subset of long-lived cytotoxic CD4(+) T-lymphocytes with proatherogenic and plaque-destabilizing properties. We hypothesized that the frequency of CD4(+) CD28(null) T-cells may be altered in T1DM and related to vascular complications. AIM: To assess the percentage of CD4(+) CD28(null) T-lymphocytes in children and adolescents with T1DM and their relation to vascular structure and glycemic control...

BACKGROUND: Elderly patients with hip fracture are at risk for cardiac complications. N-terminal pro-brain type natriuretic peptide (NT-proBNP) has been shown to predict cardiac complications in surgical patients; however, to our knowledge, only two studies have evaluated the utility of this test in patients with hip fracture. We believe it is important to assess a more accurate cutoff value of NT-proBNP with exclusion of patients with renal failure. QUESTIONS/PURPOSES: To assess the association between preoperative NT-proBNP and cardiac complications after hip fracture surgery...

OBJECTIVE: Xindening oral liquid (Xin) is a widely used traditional Chinese medicine for the treatment of chronic heart failure (CHF). However, the exact mechanisms related to its therapeutic effects against CHF remain unclear. In the present study, we investigate the effects of Xin on cardiac function in CHF rats and the possible mechanisms involved. METHODS: Transverse aortic constriction (TAC) was conducted to induce a CHF rat model in this study. Sixty male Wistar rats were randomly assigned to six groups 28 days after TAC: sham; CHF model; Xin at concentrations of 5 ml/kg, 10 mL/kg, and 20 mL/kg; and QiLi 0...
