70 (1.35 to 2.13), 0.97 (0.75 to 1.27), 1.80 (1.35 to 2.40), and 1.62 (1.07 to 2.45) for pad preparation, drilling, stimulation, and production metrics, respectively. We did not find effect modification by HFrEF or HFpEF status. Associations of most UNGD metrics with hospitalization were stronger among those with more severe HF at baseline. Three of 4 phases of UNGD activity were associated with hospitalization for HF in a large sample of patients with HF in an area of active UNGD, with similar findings by HFrEF versus HFpEF status. learn more Older patients with HFseem particularly vulnerable to adverse health impacts from UNGD activity.Three of 4 phases of UNGD activity were associated with hospitalization for HF in a large sample of patients with HF in an area of active UNGD, with similar findings by HFrEF versus HFpEF status. Older patients with HF seem particularly vulnerable to adverse health impacts from UNGD activity. There are limited published data focused on outcomes of transcatheter pulmonary valve replacement (TPVR) with either a Sapien XT or Sapien 3 (S3) valve. This study sought to report short-term outcomes in a large cohort of patients who underwent TPVR with either a Sapien XT or S3 valve. Data were entered retrospectively into a multicenter registry for patients who underwent attempted TPVR with a Sapien XT or S3 valve. Patient-related, procedural, and short-term outcomes data were characterized overall and according to type of right ventricular outflow tract (RVOT) anatomy. Twenty-three centers enrolled a total of 774 patients 397 (51%) with a native/patched RVOT; 183 (24%) with a conduit; and 194 (25%) with a bioprosthetic valve. The S3 was used in 78% of patients, and the XT was used in 22%, with most patients receiving a 29-mm (39%) or 26-mm (34%) valve. The implant was technically successful in 754 (97.4%) patients. Serious adverse events were reported in 67 patients (10%), with no difference betwee and longer follow-up will be necessary to gain insight into these issues. The ability to identify those patients at the highest phenotypic risk for long QT syndrome (LQTS)-associated life-threatening cardiac events remains suboptimal. This study sought to validate the association between electromechanical window (EMW) negativity, as derived from echocardiography, and symptomatic versus asymptomatic status in patients with LQTS. We analyzed a cohort of 651 patients with LQTS (age 26 ± 17 years; 60% females; 158 symptomatic; 51% LQTS type 1; 33% LQTS type 2; 11% LQTS type 3; 5% multiple mutations) and 50 healthy controls. EMW was calculated as the difference between the interval from QRS onset to aortic valve closure midline, as derived for continuous-wave Doppler, and the electrocardiogram-derived QT interval for the same beat. A negative EMW was found among nearly all patients with LQTS compared to controls, with more profound EMW negativity in patients with symptomatic LQTS compared to those with asymptomatic LQTS (-52 ± 38 ms vs. -18±29 ms; p<0.0001). Logistic regressi making it a routinely reported echocardiographic finding.In this validation study, patients with a history of LQTS-associated life-threatening cardiac events had a more profoundly negative EMW. EMW outperformed heart rate-corrected QT interval as a predictor of symptomatic status. EMW is now a clinically validated risk factor. In December 2019, our institution's echocardiography clinical practice committee approved use of EMW for patients with LQTS, making it a routinely reported echocardiographic finding. Microvascular dysfunction plays an important role in the pathogenesis of heart failure with preserved ejection fraction (HFpEF). However, no mechanistic link between systemic microvasculature and congestion, a central feature of the syndrome, has yet been investigated. This study aimed to investigate capillary-interstitium fluid exchange in HFpEF, including lymphatic drainage and the potential osmotic forces exerted by any hypertonic tissue Na excess. Patients with HFpEF and healthy control subjects of similar age and sex distributions (n=16 per group) underwent 1) a skin biopsy for vascular immunohistochemistry, gene expression, and chemical (water, Na , and K ) analyses; and 2) venous occlusion plethysmography to assess peripheral microvascular filtration coefficient (measuring capillary fluid extravasation) and isovolumetric pressure (above which lymphatic drainage cannot compensate for fluid extravasation). Skin biopsies in patients with HFpEF showed rarefaction of small blood and lymphatic ve lymphatic vessels in patients with HFpEF exhibit structural and molecular alterations and cannot effectively compensate for fluid extravasation and interstitial accumulation by commensurate drainage. Reduced lymphatic reserve may represent a novel therapeutic target.Peripheral lymphatic vessels in patients with HFpEF exhibit structural and molecular alterations and cannot effectively compensate for fluid extravasation and interstitial accumulation by commensurate drainage. Reduced lymphatic reserve may represent a novel therapeutic target. Patients with obstructive coronary artery disease (CAD) are at high risk for cardiovascular disease (CVD) events. However, it remains unclear whether the high risk is due to high atherosclerotic disease burden or if presence of stenosis has independent predictive value. The purpose of this study was to evaluate if obstructive CAD provides predictive value beyond its association with total calcified atherosclerotic plaque burden as assessed by coronary artery calcium (CAC). Among 23,759 symptomatic patients from the Western Denmark Heart Registry who underwent diagnostic computed tomography angiography (CTA), we assessed the risk of major CVD (myocardial infarction, stroke, and all-cause death) stratified by CAC burden and number of vessels with obstructive disease. During a median follow-up of 4.3 years, 1,054 patients experienced a first major CVD event. The event rate increased stepwise with both higher CAC scores and number of vessels with obstructive disease (by CAC scores 6.2 per 1,000 person-years (PY) for CAC=0 to 42.
