RESUMEN
INTRODUCTION: Coronary microvascular dysfunction (CMD) is common in patients with and without obstructive epicardial coronary artery disease (CAD). Risk factors for the development of CMD have not been fully elucidated, and data regarding sex-associated differences in traditional cardiovascular risk factors for obstructive CAD in patients with CMD are lacking. METHODS: In this single-center, prospective registry, we enrolled patients with nonobstructive CAD undergoing clinically indicated invasive assessment of coronary microvascular function between November 2019 and March 2023. Associations between coronary microvascular dysfunction, traditional cardiovascular risk factors, and sex were assessed using univariate and multivariate regression models. RESULTS: Overall, 245 patients with nonobstructive CAD were included in the analysis (62.9% female; median age 68 (interquartile range: 59, 75). Microvascular dysfunction was diagnosed in 141 patients (57.5%). The prevalence of microvascular dysfunction was similar in women and men (59.0% vs. 57.0%; p = 0.77). No association was found between traditional risk factors for coronary atherosclerosis and CMD regardless of whether CMD was structural or functional. In women, but not in men, older age and the presence of previous ischemic heart disease were associated with lower coronary flow reserve (ß = -0.29; p < 0.01 and ß = -0.15; p = 0.05, respectively) and lower resistive reserve ratio (ß = -0.28; p < 0.01 and ß = -0.17; p = 0.04, respectively). CONCLUSION: For the entire population, no association was found between coronary microvascular dysfunction and traditional risk factors for coronary atherosclerosis. In women only, older age and previous ischemic heart disease were associated with coronary microvascular dysfunction. Larger studies are needed to elucidate risk factors for CMD.
RESUMEN
BACKGROUND: Mitral valve-in-valve (ViV) and valve-in-ring (ViR) are alternatives to surgical reoperation in patients with recurrent mitral valve failure after previous surgical valve repair or replacement. Our aim was to perform a large-scale analysis examining midterm outcomes after mitral ViV and ViR. METHODS: Patients undergoing mitral ViV and ViR were enrolled in the Valve-in-Valve International Data Registry. Cases were performed between March 2006 and March 2020. Clinical endpoints are reported according to the Mitral Valve Academic Research Consortium (MVARC) definitions. Significant residual mitral stenosis (MS) was defined as mean gradient ≥10 mm Hg and significant residual mitral regurgitation (MR) as ≥ moderate. RESULTS: A total of 1079 patients (857 ViV, 222 ViR; mean age 73.5±12.5 years; 40.8% male) from 90 centers were included. Median STS-PROM score 8.6%; median clinical follow-up 492 days (interquartile range, 76-996); median echocardiographic follow-up for patients that survived 1 year was 772.5 days (interquartile range, 510-1211.75). Four-year Kaplan-Meier survival rate was 62.5% in ViV versus 49.5% for ViR (P<0.001). Mean gradient across the mitral valve postprocedure was 5.7±2.8 mm Hg (≥5 mm Hg; 61.4% of patients). Significant residual MS occurred in 8.2% of the ViV and 12.0% of the ViR patients (P=0.09). Significant residual MR was more common in ViR patients (16.6% versus 3.1%; P<0.001) and was associated with lower survival at 4 years (35.1% versus 61.6%; P=0.02). The rates of Mitral Valve Academic Research Consortium-defined device success were low for both procedures (39.4% total; 32.0% ViR versus 41.3% ViV; P=0.01), mostly related to having postprocedural mean gradient ≥5 mm Hg. Correlates for residual MS were smaller true internal diameter, younger age, and larger body mass index. The only correlate for residual MR was ViR. Significant residual MS (subhazard ratio, 4.67; 95% CI, 1.74-12.56; P=0.002) and significant residual MR (subhazard ratio, 7.88; 95% CI, 2.88-21.53; P<0.001) were both independently associated with repeat mitral valve replacement. CONCLUSIONS: Significant residual MS and/or MR were not infrequent after mitral ViV and ViR procedures and were both associated with a need for repeat valve replacement. Strategies to improve postprocedural hemodynamics in mitral ViV and ViR should be further explored.

INTRODUCTION: Ostial coronary lesions are a subset of proximal coronary lesions, which are relatively more difficult to treat and were associated with worse clinical outcomes in the early percutaneous coronary intervention (PCI) era. Data regarding the outcomes of ostial lesions' PCI in the contemporary era are lacking. METHODS: We conducted a single-center, all-comer, prospective registry study, enrolling patients undergoing PCI with the use of contemporary drug-eluting stents (DES) between July 2016 and February 2018. Included in the present analysis were only patients treated for proximal lesions. Clinical outcomes were compared between patients undergoing PCI of ostial versus proximal nonostial lesions. The primary endpoint was target vessel revascularization (TVR). Secondary endpoints included target lesion revascularization (TLR) and major cardiovascular adverse events (MACE) at 12 months. RESULTS: A total of 334 (84.7% male, 67.3 ± 10.7 years) patients were included, of which 91 patients were treated for ostial lesions and 243 were treated for proximal nonostial lesions. Baseline and procedural characteristics were similar between the two groups. At 12 months, TVR and TLR were numerically higher among patients undergoing PCI of ostial versus nonostial lesions without reaching statistical significance (5.5% vs. 3.3%; p = 0.35 and 4.4% vs. 2.5%; p = 0.47, respectively). The rate of MACE was similar between the two groups. CONCLUSION: In patients undergoing PCI with the use of contemporary DES, clinical outcomes were similar among patients treated for ostial compared to proximal nonostial lesions. Larger studies are required to further evaluate the performance of contemporary DES in this subset of lesions.

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR) is a simple and cost-effective marker of inflammation. This marker has been shown to predict cardiac arrhythmias, progression of valvular heart disease, congestive heart failure decompensation, acute kidney injury, and mortality in cardiovascular patients. The pathologic process of aortic stenosis includes chronic inflammation of the valve and therefore biomarkers of inflammation might offer additive prognostic value. OBJECTIVES: To evaluate NLR and its association with long term mortality in transcatheter aortic valve implantation (TAVI) patients. METHODS: We evaluated data of 1152 consecutive patient from the Tel Aviv Medical Center TAVI registry who underwent TAVI. Data included baseline clinical, demographic, and echocardiographic findings; procedural complications; and post-procedure mortality. Patients were compared by using the median NLR value (4.1) and evaluated for long-term mortality. RESULTS: Patients with NLR above the median had higher mortality rates (26.4% vs. 16.3%, P < 0.001) at 3 years post-procedure. A multivariable analysis found NLR to be an independent risk factor for mortality (hazard ratio = 1.47, 95% confidence interval 1.09-1.99, P = 0.013). In addition, high NLR was linked to complicationsduring and after the procedure. CONCLUSIONS: NLR is an independent prognostic marker among TAVI patients. This marker may represent an increased inflammatory response and should be added to previous known prognostic factors.

BACKGROUND: Information on the cardiac manifestations of coronavirus disease 2019 (COVID-19) is scarce. We performed a systematic and comprehensive echocardiographic evaluation of consecutive patients hospitalized with COVID-19 infection. METHODS: One hundred consecutive patients diagnosed with COVID-19 infection underwent complete echocardiographic evaluation within 24 hours of admission and were compared with reference values. Echocardiographic studies included left ventricular (LV) systolic and diastolic function and valve hemodynamics and right ventricular (RV) assessment, as well as lung ultrasound. A second examination was performed in case of clinical deterioration. RESULTS: Thirty-two patients (32%) had a normal echocardiogram at baseline. The most common cardiac pathology was RV dilatation and dysfunction (observed in 39% of patients), followed by LV diastolic dysfunction (16%) and LV systolic dysfunction (10%). Patients with elevated troponin (20%) or worse clinical condition did not demonstrate any significant difference in LV systolic function compared with patients with normal troponin or better clinical condition, but they had worse RV function. Clinical deterioration occurred in 20% of patients. In these patients, the most common echocardiographic abnormality at follow-up was RV function deterioration (12 patients), followed by LV systolic and diastolic deterioration (in 5 patients). Femoral deep vein thrombosis was diagnosed in 5 of 12 patients with RV failure. CONCLUSIONS: In COVID-19 infection, LV systolic function is preserved in the majority of patients, but LV diastolic function and RV function are impaired. Elevated troponin and poorer clinical grade are associated with worse RV function. In patients presenting with clinical deterioration at follow-up, acute RV dysfunction, with or without deep vein thrombosis, is more common, but acute LV systolic dysfunction was noted in ≈20%.

OBJECTIVES: Right ventricular (RV) dysfunction and tricuspid regurgitation (TR) are associated with adverse outcomes in severe aortic stenosis (AS) patients. Our aim was to evaluate the association between ≥moderate TR and RV dysfunction on long-term mortality following transcatheter aortic valve replacement (TAVR). METHODS: A retrospective analysis of the Israeli multicenter TAVR registry among 4,344 consecutive patients, with all-cause mortality as the main outcome measure. RESULTS: Echocardiographic assessment of TR grade and RV dysfunction was available for 3,733 and 1,850 patients, of whom ≥moderate TR and RV dysfunction was noted for 478(13%) and 78(4%), respectively. The mean follow-up time was 2.9 ± 2.3 years. In univariate models, ≥Moderate TR and ≥moderate RV dysfunction were associated with increased long-term mortality (HR 1.45, 95% CI 1.24-1.69, p < .001 and HR 1.73, 95% CI 1.21-2.47, p = 0.003, respectively). These finding did not remained significant after adjusting to echocardiographic parameters. A subset of patients with no improvement in RV function had the highest long-term mortality risk (HR 3.3, 95% CI 1.95-5.7, p < .001). CONCLUSION: When adjusted to multiple echocardiographic characteristics baseline ≥Moderate TR and ≥moderate RV dysfunction were not associated with long-term mortality following TAVR. Persistent RV dysfunction following TAVR was associated with the highest risk for mortality.

BACKGROUND: Increased survival among active cancer patients exposes a wide range of side effects, including cardiotoxicity, manifested by systolic dysfunction and associated with morbidity and mortality. Early diagnosis of subclinical function changes and cardiac damage is essential in the management of these patients. Diastolic dysfunction is considered common among cancer patients; however, its effect on systolic dysfunction or mortality is still unknown. METHODS: Data were collected as part of the Israel Cardio-Oncology Registry, enrolling and prospectively following all patients evaluated in the cardio-oncology clinic in the Tel Aviv Sourasky Medical Center. All patients underwent echocardiographic examinations including evaluation of diastolic parameters and global longitudinal strain (GLS). Systolic dysfunction was defined as either an absolute reduction >10% in left ventricular ejection fraction to a value below 53% or GLS relative reduction >10% between the 1st and 3rd echocardiography examinations. RESULTS: Overall, 190 active cancer patients were included, with a mean age of 58 ± 15 years and a female predominance (78%). During a median follow-up of 243 days (interquartile ranges [IQR]: 164-401 days), 62 (33%) patients developed systolic dysfunction. Over a median follow-up of 789 days (IQR: 521-968 days), 29 (15%) patients died. There were no significant differences in baseline cardiac risk factors between the groups. Using multivariate analysis, E/e' lateral and e' lateral emerged as significantly associated with systolic dysfunction development and all-cause mortality (P = .015). CONCLUSION: Among active cancer patients, evaluation of diastolic function may provide an early marker for the development of systolic dysfunction, as well as all-cause mortality.

BACKGROUND: Elevated C-reactive protein (CRP) was shown to be associated with an increased risk for new-onset atrial fibrillation (AF) in ST elevation myocardial infarction (STEMI) patients undergoing primary percutaneous coronary intervention (PCI); however, the optimal time frame to measure CRP for risk stratification is not known. OBJECTIVES: To evaluate the relation between the change in CRP over time (CRP velocity [CRPv]) and new-onset AF among STEMI patients treated with primary PCI. METHODS: We included 801 STEMI patients who underwent PCI between 2007 and 2017 and had their CRP measured with a wide range assay (wr-CRP) at least twice during the 24 hours after admission. CRPv was defined as the change in wr-CRP concentration (mg/l) divided by the change in time (in hours) between the two measurements. Patient medical records were reviewed for occurrence of new-onset AF. RESULTS: New onset AF occurred in 45 patients (6%). Patients with new onset AF had significantly higher median CRPv (1.27 vs. 0.43 mg/l/h, P = 0.002). New-onset AF during hospitalization occurred in 3.4%, 4.5 %, and 9.1% of patients in the first, second and third CRPv tertiles, respectively (P for trend = 0.006). In a multivariable logistic regression, adjusting for clinical variables the odds ratios for new onset AF was 1.93 (95% confidence interval 1.0-3.59, P = 0.04) for patients in the third CRPv tertile. CONCLUSIONS: CRPv might be an independent and rapidly measurable biomarker for new-onset AF following primary PCI in STEMI patients.

INTRODUCTION: Despite the impressive decline in mortality from atherosclerotic cardiovascular diseases (ASCVD), these diseases still account for a large proportion of the overall morbidity and mortality worldwide. A vast amount of research has demonstrated the key role played by circulating lipoproteins, and especially low-density lipoprotein (LDL), in the etiology of atherosclerosis, and numerous studies have proven the efficacy of interventions that lower the atherogenic lipoproteins in reducing morbidity and mortality from ASCVD. While previous guidelines placed an emphasis on the use HMG-CoA reductase inhibitors (statins) for the treatment of dyslipidemia, recent studies have shown that other LDL cholesterol lowering drugs, including ezetimibe and the PCSK9 inhibitors, can provide additional benefit when used in combination with (and in certain cases instead of) statins. These studies have also shown that blood LDL cholesterol levels lower than previously recommended targets provide additional benefit, without evidence of a threshold beyond which the benefit ceases and without excess adverse effects. The updated guidelines were formulated by a committee that consisted of representatives from the Israeli Society for the Research, Prevention and Treatment of Atherosclerosis, the Israel Society of Internal Medicine, the Israeli Heart Association, the Israeli Neurology Association and the Israel Association of Family Medicine. They provide recommendations for revised risk stratification of patients, novel target goals, and the use of evidence-based treatment and follow-up strategies with reference to specific patient sub-groups.

BACKGROUND: Chemotherapy induced cardio-toxicity has been recognized as a serious side effect since the first introduction to anthracyclines (ANT). Cardio-toxicity among patients with breast cancer is well studied but the impact on patients with sarcoma is limited, even though they are exposed to higher ANT doses. The commonly used term for cardio-toxicity is cancer therapeutics related cardiac dysfunction (CTRCD), defined as a left ventricular ejection fraction (LVEF) reduction of > 10%, to a value below 53%. The aim of our study was to estimate the prevalence of CTRCD in patients diagnosed with sarcoma and to describe the baseline risk factors and echocardiography parameters among that population. METHODS: Data were collected as part of the Israel Cardio-Oncology Registry (ICOR), enrolling all patients evaluated in the cardio-oncology clinic at our institution. The registry was approved by the local ethics committee and is registered in clinicaltrials.gov (Identifier: NCT02818517). All sarcoma patients were enrolled and divided into two groups - CTRCD group vs. non-CTRCD group. RESULTS: Among 43 consecutive patients, 6 (14%) developed CTRCD. Baseline cardiac risk factors were more frequent among the non-CTRCD group. Elevated left ventricular end systolic diameter and reduced Global Longitudinal Strain were observed among the CTRCD group. During follow-up, 2 (33%) patients died in the CTRCD group vs. 3 (8.1%) patients in the non-CTRCD group. CONCLUSIONS: CTRCD is an important concern among patients with sarcoma, regardless of baseline risk factors. Echocardiography parameters may provide an early diagnosis of cardio-toxicity.

BACKGROUND: Acute kidney injury (AKI) complicating transcatheter aortic valve implantation (TAVI) is relatively frequent and associated with significant morbidity. Previous studies have shown a higher 30-day and 1-year mortality risk in patients with periprocedural AKI. Our aim was to identify the prognostic impact of periprocedural AKI on long-term follow-up. METHODS: This is a single-center prospective study evaluating patients undergoing TAVI for severe aortic stenosis. AKI was defined according to the Valve Academic Research Consortium 2 definition, as an absolute increase in serum creatinine ≥0.3 mg/dL or an increase >50% within the first week following TAVI. Mortality data were compared between patients who developed AKI and those who did not. Logistic and Cox regressions were used for survival analysis. RESULTS: The final analysis included 1086 consecutive TAVI patients. AKI occurred in 201 patients (18.5%). During the follow-up period, 289 patients died. AKI was associated with an increased risk of 30-day mortality {4.5 versus 1.9% in the non-AKI group; hazard ratio [HR] 3.70 [95% confidence interval (CI) 1.35-10.13]}. Although 1-year mortality was higher in the AKI group in univariate analysis, it was not significant after a multivariate regression. AKI was a strong predictor of longer-term mortality [42.3 versus 22.7% for 7-year mortality; HR 1.71 (95% CI 1.30-2.25)]. In 189 of 201 patients we had data regarding recovery from AKI up to 30 days after discharge. In patients with recovery from AKI, the mortality rate was lower (38.2 versus 56.6% in the nonrecovery group; P = 0.022). CONCLUSIONS: Periprocedural AKI following TAVI is a strong risk factor for short-term as well as long-term mortality (up to 7 years). Therefore more effort is needed to reduce this complication.

BACKGROUND: Although diastolic dysfunction is common among patients treated with cancer therapy, no clear evidence has been shown that it predicts systolic dysfunction. This study evaluated the correlation of diastolic strain time (Dst) with the routine echocardiography diastolic parameters and estimated its role in the early detection of cardiotoxicity among patients with active breast cancer. METHODS: Data were collected as part of the Israel Cardio-Oncology Registry (ICOR), a prospective registry enrolling all adult patients referred to the cardio-oncology clinic. All patients with breast cancer, planned for Doxorubicin therapy, were included. Echocardiography, including global longitudinal systolic strain (GLS) and Dst, was assessed at baseline before chemotherapy (T1), during Doxorubicin therapy (T2) and after the completion of Doxorubicin therapy (T3). Cardiotoxicity was determined by GLS relative reduction of ≥15%. Dst was assessed as the time measured (ms) of the myocardium lengthening during diastole. RESULTS: Among 69 patients, 67 (97.1%) were females with a mean age of 52 ± 13 years. Dst was significantly associated with the routine diastolic parameters. Significant GLS reduction was observed in 10 (20%) patients at T3. Both in a univariate and a multivariate analyses, the change in Ds basal time from T1 to T2 emerged to be significantly associated with GLS reduction at T3 (P < .04). CONCLUSIONS: Among breast cancer patients, Dst showed high correlation to the routine diastolic echocardiography parameters. Change in Ds basal time emerged associated with clinically significant systolic dysfunction as measured by GLS reduction.

AIMS: Acute kidney injury (AKI) is a common complication following transcatheter aortic valve implantation (TAVI) and is associated with increased risk for short- and long-term mortality. In patients undergoing percutaneous coronary intervention (PCI), forced diuresis with matched hydration has been shown to reduce the incidence of AKI by â¼50%. The aim of the present study was to evaluate whether forced diuresis with matched intravenous hydration reduces AKI in patients undergoing TAVI. METHODS AND RESULTS: Reducing Acute Kidney Injury (REDUCE-AKI) was a single-centre, prospective, randomized, double-blind sham-controlled clinical trial, designed to examine the effect of an automated matched saline infusion with urine output for the prevention of AKI in patients undergoing TAVI. A total of 136 TAVI patients were randomized, 68 in each group. Mean age was 83.9 ± 5 years and 41.2% were males. There were no differences in baseline characteristics between the two groups. The rate of AKI was not statistically different between the groups (25% in the active group vs. 19.1% in the sham group, P = 0.408). There was a significant increase in long-term mortality in the active group (27.9% vs. 13. 2% HR 3.744, 95% CI 1.51-9.28; P = 0.004). The study was terminated prematurely by the Data Safety Monitoring Board for futility and a possible signal of harm. CONCLUSIONS: Unlike in PCI, forced diuresis with matched hydration does not prevent AKI in patients undergoing TAVI, and might be associated with increased long-term mortality. Future studies should focus on understanding the mechanisms behind these findings. CLINICALTRIALS.GOV REGISTRATION: NCT01866800, 30 April 2013.

BACKGROUND: Progress in the treatment of breast cancer has led to substantial improvement in survival, but at the cost of increased side effects, with cardiotoxicity being the most significant one. The commonly used definition is cancer therapeutics-related cardiac dysfunction (CTRCD), defined as a left ventricular ejection fraction reduction of > 10%, to a value below 53%. Recent studies have implied that the incidence of CTRCD among patients with breast cancer is decreasing due to lower doses of anthracyclines and low association to trastuzumab and pertuzumab treatment. OBJECTIVES: To evaluate the prevalence of CTRCD among patients with active breast cancer and to identify significant associates for its development. METHODS: Data were collected as part of the Israel Cardio-Oncology Registry, which enrolls all patients who are evaluated at the cardio-oncology clinic at our institution. Patients were divided to two groups: CTRCD and no-CTRCD. RESULTS: Among 103 consecutive patients, five (5%) developed CTRCD. There were no significant differences in the baseline cardiac risk factors between the groups. Significant correlations of CTRCD included treatment with trastuzumab (P = 0.001) or pertuzumab (P < 0.001), lower baseline global longitudinal strain (GLS) (P = 0.016), increased left ventricular end systolic diameter (P < 0.001), and lower e' septal (P < 0.001). CONCLUSIONS: CTRCD is an important concern among patients with active breast cancer, regardless of baseline risk factors, and is associated with trastuzumab and pertuzumab treatment. Early GLS evaluation may contribute to risk stratification and allow deployment of cardioprotective treatment.

Bioprostheses are prone to structural valve degeneration, resulting in limited long-term durability. A significant challenge when comparing the durability of different types of bioprostheses is the lack of a standardized terminology for the definition of a degenerated valve. This issue becomes especially important when we try to compare the degeneration rate of surgically inserted and transcatheter bioprosthetic valves. This document, by the VIVID (Valve-in-Valve International Data), proposes practical and standardized definitions of valve degeneration and provides recommendations for the timing of clinical and imaging follow-up assessments accordingly. Its goal is to improve the quality of research and clinical care for patients with deteriorated bioprostheses by providing objective and strict criteria that can be utilized in future clinical trials. We hope that the adoption of these criteria by both the cardiological and surgical communities will lead to improved comparability and interpretation of durability analyses.

Inflammation participates in the initiation and progression of atherosclerotic cardiovascular disease, and it is a critical inciting factor leading to acute ischemic events. Evidence has shown that certain anti-inflammatory medications used to treat non-atherosclerotic inflammatory diseases reduce cardiovascular events. This article reviews evidence that commonly used anti-inflammatory therapies (colchicine, allopurinol, methotrexate), reduce cardiovascular events. We discuss potential mechanisms of action, efficacy, and safety of these therapies and propose a clinical trials design to investigate their efficacy.

BACKGROUND: Limited information exists on whether changes in medical practices over the study decades have affected the outcomes of acute coronary syndrome (ACS) patients who undergo early coronary artery bypass surgery (CABG) during index hospitalisation. METHODS: Data on trends for early CABG referral and associated outcomes were obtained among 11,485 ACS patients enrolled in the biennial Acute Coronary Syndrome Israeli Surveys (ACSIS) 2000-2010. RESULTS: Among 11,485 patients, 566 (5%) were referred to early CABG. These patients displayed higher risk characteristics, including Killip class >II, anterior myocardial infarction, greater left ventricular dysfunction, and more frequent use of mechanical ventilation and intra-aortic balloon pump (all p<0.01). Nevertheless, mortality rates of patients referred to early CABG vs. treated with percutaneous coronary intervention (PCI) or medically, was similar (11.4% vs. 10.2%; log-rank p-value=0.40). There was a significant decline in the referral trend over the study decade (6.7% - 1.7%; p<0.001). One year survival was similar between patients referred to early CABG during the late (years: 2006-2010) vs. early (years: 2000-2005) period (85.7% vs. 90%; log-rank p-value=0.15), whereas, among patients who didn't undergo early CABG, and underwent percutaneous coronary intervention (PCI) or medical management only, enrolment during the late periods was associated with a significant survival benefit (91.5% vs. 88.1%; log-rank p-value<0.001). CONCLUSIONS: Over the study decade there was a significant decline in referral for early CABG, without a difference in the one-year mortality between the early and non-early CABG group.

BACKGROUND: Most patients undergoing Transcatheter aortic valve implantation (TAVR) are elderly with significant co-morbidities and there is limited information available regarding factors that influence length of stay (LOS) post-procedure. The aim of this study was to identify the patient, and procedural factors that affect post-TAVR LOS using a contemporary multinational registry. METHODS: We conducted a retrospective cohort study, with patients recruited from three high volume tertiary institutions. The primary outcome was the LOS post-TAVR procedure. We examined patient and procedural factors in a cause-specific Cox multivariable regression model to elucidate their effect on LOS, accounting for the competing risk of post-procedural death. Hazard ratios (HR) greater than 1 indicate a shorter LOS, while HRs less than 1 indicate a longer LOS. RESULTS: The cohort consisted of 809 patients. Patient factors associated with longer LOS were older age, prior atrial fibrillation, and greater patient urgency. Patient factors associated with shorter LOS were lower NYHA class, higher ejection fraction and higher mean aortic valve gradients. Procedural characteristics associated with shorter LOS were conscious sedation (HR = 1.19, 95% CI 1.06-1.35, p = 0.004). Transapical access was associated with prolonged LOS (HR = 0.49, 95% CI 0.41-0.58, p < 0.001). CONCLUSION: This multicenter study identified potentially modifiable patient and procedural factors associated with a prolonged LOS. Future research is needed to determine if interventions focused on these factors will translate to a shorter LOS.

BACKGROUND: Sex differences in heart diseases, including acute coronary syndrome, congestive heart failure, and atrial fibrillation, have been studied extensively. However, data are lacking regarding sex differences in pericarditis and myopericarditis patients. OBJECTIVES: The purpose of the study was to evaluate whether there are sex differences in pericarditis and myopericarditis patients as well. METHODS: We performed a retrospective, single-center observational study that included 200 consecutive patients hospitalized with idiopathic pericarditis or myopericarditis from January 2012 to April 2014. Patients were evaluated for sex differences in prevalence, clinical presentation, laboratory variables, and outcome. We excluded patients with a known cause for pericarditis. RESULTS: Among 200 consecutive patients, 55 (27%) were female. Compared with men, women were significantly older (60±19 years vs 46±19 years, P<.001) and had a higher rate of chronic medical conditions. Myopericarditis was significantly more common among men (51% vs 25%, P=.001). Accordingly, men had significantly higher levels of peak troponin (6.8±17 ng/mL vs 0.9±2.6 ng/mL, P<.001), whereas women presented more frequently with pericardial effusion (68% vs 45%, P=.006). Interestingly, women had a significantly lower rate of hospitalization in the cardiology department (42% vs 63%, P=.015). Overall, there were no significant differences in ejection fraction, type of treatment, complications, or in-hospital mortality. CONCLUSIONS: Most patients admitted with acute idiopathic pericarditis are male. In addition, men have a higher prevalence of myocardial involvement. Significant sex differences exist in laboratory variables and in hospital management; however, the outcome is similar and favorable in both sexes.

BACKGROUND: The optimal method of coronary revascularization among patients with diabetes mellitus (DM) and multivessel coronary artery disease (CAD) complicated by chronic kidney disease (CKD) remains unknown. PURPOSE: To examine the impact of coronary artery bypass surgery (CABG) vs. percutaneous coronary intervention (PCI) on cardiovascular outcomes in patients with diabetes with and without CKD. METHODS: We conducted an 'as-treated' subgroup analysis of the FREEDOM trial to examine the therapeutic efficacy of CABG vs. PCI among patients with DM stratified by the presence (n = 451) or absence (n = 1392) of CKD. We defined CKD as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73m2. Baseline characteristics and clinical outcomes were compared between PCI and CABG groups within each CKD stratum. The primary endpoint was the composite occurrence of all-cause death, stroke or myocardial infarction [major adverse cardiovascular and cerebrovascular events (MACCE)]. Event rates were estimated at 5 years using the Kaplan-Meier approach and hazard ratios (HRs) for CABG (vs. PCI) were generated using Cox regression. RESULTS: Patients with CKD (mean eGFR 47 mL/min/1.73m2) were older and more often female compared to those without renal impairment. Over a median follow-up of 3.8 years, the effect of CABG on MACCE was consistent among those with CKD (26.0% vs. 35.6%; HR [95% CI]: 0.73 [0.50-1.05]) and without CKD (16.2% vs. 23.6%; HR [95% CI)]: 0.76 [0.58-1.00]) with no evidence of interaction (pint = 0.83). Stroke rates were non-significantly higher with CABG whereas rates of MI and repeat revascularization were significantly reduced with CABG in both groups. CONCLUSIONS: Compared to PCI, the effects of CABG on long-term risks for MACCE observed in the FREEDOM trial are preserved among patients with mild to moderate CKD.
