These trends in the geographic range and abundance of nymphs correspond to both the geographic expansion of human Lyme disease cases and increases in incidence rates. Analytic models fitted to these data incorporating time, space, and environmental factors, accurately identified drivers of the observed changes in nymphal occurrence and abundance. These models accounted for the spatial and temporal variation in the occurrence and abundance of nymphs and can accurately predict nymphal population patterns in future years. Forecasting disease risk at fine spatial scales prior to the transmission season can influence both public health mitigation strategies and individual behaviours, potentially impacting tick-borne disease risk and subsequently human disease incidence.Data regarding the potential influence of gender on outcomes of rotational atherectomy (RA) percutaneous coronary intervention (PCI) are scarce and conflicting. Using the Euro4C registry, an international prospective multicentric registry of RA PCI, we evaluated the influence of gender on clinical outcomes of RA PCI. Between October 2016 and July 2018, 966 patients were included. In them, 267 (27.6%) were females. Female patients were older than males (77.7 years old ± 9.8 vs 73.3 ± 9.5 years old respectively, p less then 0.001) had a poorer renal function (43,1% of females had a GFR less then 60 ml/min1.73m² vs 30.4% of males, p less then 0.001) and were more frequently admitted for an acute coronary syndrome (32.2% vs 22.3% p = 0.002). During RA procedure, women were less likely to be treated by radial approach (65.0% vs 74.4%, p = 0.004). In-hospital major adverse cardiac event rate-defined as cardiovascular death, myocardial infarction, stroke/transient ischemic attack, target lesion revascularization, and coronary artery bypass grafting surgery-was higher in the female group (7.1% vs 3.7%, p = 0.043). However, coronary perforation, dissection, slow/low flow and tamponade did not significantly differ in gender, neither did cardiovascular medications at discharge. At 1 year follow-up, rate of major adverse cardiac event was 18.4% in the female group vs 11.2% in the male group (adjusted Hazard Ratio 1.82 [1.24 to 2.67], p = 0.002). No significant bleeding differences were observed in gender, neither in hospital, nor during follow-up. In conclusion women had worse clinical outcomes following RA PCI during hospitalization and at 1 year follow-up than did men.Limited data are available regarding the independent prognostic role of preoperative atrial fibrillation (AF) after transcatheter mitral valve repair with MitraClip. We sought to evaluate the impact of preoperative AF in patients with heart failure (HF) and concomitant secondary mitral regurgitation (MR) after MitraClip treatment. The study included 605 patients with significant secondary MR from a multicenter international registry. Patients were stratified into 2 groups according to the presence or absence of preoperative AF. Primary end point was 5-year overall death, secondary end points were 5-year cardiac death and first re-hospitalization for HF. To account for baseline differences, patients were propensity score matched 11. The overall prevalence of preoperative AF was 44%. At 5-year Kaplan-Meier analysis, compared with patients without AF, those with AF had significantly more adverse events in term of overall death (67% vs 43%; HR 1.84, log-rank p less then 0.001) and cardiac death (56% vs 29%; HR 2.11, log-rank p less then 0.001) and re-hospitalization for HF (63% vs 52%; HR 1.33, log-rank p = 0.048). Multivariate analysis identified AF as independent predictor of worse outcome in term of primary end point (HR 1.729, 95% C.I. 1.060 to 2.821; p = 0.028). After propensity score matching, patients with AF had higher rates of death and cardiac mortality but similar rates of re-hospitalization for HF. In conclusion, in patients with HF undergoing MitraClip treatment for secondary MR, preoperative AF is common and an unfavourable predictor of 5-year death and cardiac death. However, AF did not affect the frequency of re-hospitalization for HF.Breast cancer is the most commonly diagnosed cancer in women and radiotherapy is a widely used treatment approach. However, there is an increased risk of coronary artery disease and cardiac death in women treated with radiotherapy. The present study was undertaken to clarify the relation between radiotherapy and coronary disease in women with previous breast irradiation using coronary computed tomographic angiography (CCTA). We conducted a retrospective analysis of women with a history of right or left-sided breast cancer (RBC; LBC) treated with radiotherapy who subsequently underwent CCTA. RBC patients who had reduced radiation doses to the myocardium served as controls. Patients (n = 6,593) with a history of nonmetastatic breast cancer treated with radiotherapy were screened for completion of CCTA; 49 LBC and 45 RBC women were identified. Age and risk factor matched patients with LBC had higher rates of coronary disease compared with RBC patients; left anterior descending (LAD) coronary artery (76% vs 31% [p less then 0.001]), left circumflex (33% vs. 6.7% [p = 0.004]), and right coronary artery (37% vs 13% [p = 0.018]). Mean LAD radiation dose and mean heart dose strongly correlated with coronary disease, with a 21% higher incidence of disease in the LAD per Gy for mean LAD dose and a 95% higher incidence of disease in the LAD per Gy for mean heart dose. In conclusion, LBC patients treated with radiotherapy have a significantly higher incidence of coronary disease when compared with a matched group of patients treated for RBC. Radiation doses correlated with the incidence of coronary disease.The American Society of Echocardiography and/or the European Association of Cardiovascular Imaging recommend a conventional algorithm for estimating left ventricular (LV) filling pressure in heart failure. However, several patients are classed as "indeterminate" due to their LV filling pressures being impossible to calculate. We investigated whether our new echocardiographic algorithm can predict clinical outcomes in patients with heart failure with preserved ejection fraction (HFpEF). We enrolled 754 consecutive patients from the PURSUIT-HFpEF registry. We used the new algorithm to divide them into 2 groups; a normal LV filling pressure group (N group) and a high LV filling pressure group (H group). The H group consisted of 342 patients. Over a mean follow-up of 342 days, 185 patients reached the primary composite end point (157 readmissions for worsening heart failure and 43 cardiovascular deaths). In a multivariable Cox analysis, being in the H group was significantly associated with an increased rate of cardiac events compared with the N group (hazard ratio 1.71; 95% confidence interval 1.17 to 2.50, p = 0.006). There were 56 patients (7%) who were assigned to "indeterminate" with the conventional algorithm. Using the new algorithm, we reclassified 16 patients (29%) into the H group and 40 patients (71%) into the N group. The Kaplan-Meier curves showed the reclassified H group had a significantly higher incidence of cardiac events than those assigned to the N group (p less then 0.01). In conclusion, the present study demonstrated LV filling pressure assessed by our algorithm can predict clinical outcomes in patients with HFpEF.As transcatheter aortic valve Implantation (TAVI) moves to younger and lower risk patients with longer life expectancy, the long-term durability of TAVI is becoming an increasingly relevant issue. We sought to evaluate the long-term clinical outcome and prosthesis performance of the CoreValve self-expandable valve. Clinical registry of 182 patients consecutively treated with TAVI in a tertiary center from January 2009 to July 2017. Of these, 111 died during an average follow-up (FU) of 1,026 ± 812 days (median IQR 745, 477 to 1,400 days; longest survival 11 years; 61% mortality at Kaplan-Meier analysis). At 1 month, functional profile improved in all survivors, with 93.9% of them achieving NYHA class I or II. At Cox analysis, the Society of Thoracic Surgeons score (HR 1.55; p = 0.001), left ventricular ejection fraction 0.05). Most patients had none and/or trivial (34%), or mild (58%), fewer had moderate (8%) and none had severe perivalvular leak, without significant change during FU. At 11 years, cumulative incidence of bioprosthetic valve failure and moderate structural valve deterioration (SVD) were 2.9% (95% CI 0.8% to 10%) and 9.3% (95% CI 3.3% to 26.7%), respectively. In conclusion, our registry confirmed that TAVI with the self-expandable CoreValve system was associated with favorable long-term clinical outcomes, with a reassuring low rate of significant bioprosthetic valve failure and moderate SVD.The present study aimed to examine differences in left- and right atrial characteristics between atrial fibrillation (AF) patients with and without chronic obstructive pulmonary disease (COPD). For this, 420 patients (mean age 68 ± 10 years, 73% female) with first diagnosis of AF and baseline echocardiography were included. Of these, 143 COPD patients were compared with 277 patients without COPD matched by age, gender and body surface area. Additionally 38 healthy controls without cardiovascular risk factors, matched for age, were included. For all 3 groups, left atrial (LA) volumes and diameter, LA reservoir strain (LASr), left ventricular ejection fraction (LVEF), right atrial (RA) area and diameter, RA reservoir strain (RASr) and tricuspid annular plane systolic excursion were evaluated on transthoracic echocardiography. Baseline characteristics were similar in patients with and without COPD except for smoking and a history of heart failure (42% vs 11%, p less then 0.001 and 48% vs 37%, p = 0.036 for COPD and non-COPD patients, respectively). AZ20 in vitro Also, COPD patients less often used β-blockers (63% vs 75%, p = 0.017). There were no significant differences in LVEF, LA volume and RA area between COPD and non-COPD patients. Compared to the controls, AF patients had impaired LVEF, LASr and RASr. Only RASr was significantly worse in COPD patients as compared to non-COPD patients (15.3% [9.0 to 25.1] vs 19.6% [11.8 to 28.5], p = 0.013). Additionally, a trend towards worse RASr was observed with increasing COPD severity. In conclusion, AF patients with concomitant COPD have more impaired RA function compared to patients without COPD but with similar atrial size and LA function.Low systolic blood pressure (SBP) was previously suggested to be a marker for heart failure and mortality in patients with low left ventricular ejection fraction. We aimed to explore the association of SBP on risk of ventricular tachyarrhythmias (VTA) and atrial arrhythmias as well as appropriate and inappropriate Implantable Cardioverter Defibrillator (ICD) therapy. The study population comprised 1,481 of 1,500 (99%) patients enrolled in the Multicenter Automatic Defibrillator Implantation Trial - Reduce Inappropriate Therapy trial. Multivariate Cox proportional hazards regression modeling was used to identify the association of baseline SBP (recorded prior to ICD implantation) with the risk of VTA > 170 beats/min during follow-up (primary end point) and atrial arrhythmia, appropriate and inappropriate ICD therapy, hospitalization and death (secondary end points). SBP was dichotomized at 120 mm Hg (approximate mean and median) and was also assessed as a continuous measure. Multivariate analysis showed that each 10 mm Hg decrement in SBP was associated with corresponding 11% increased risk for VTA (p = 0.
