RESUMEN

BACKGROUND: Recent studies suggest that aortic valve replacement (AVR) remains underutilized. AIMS: Investigate the potential role of non-referral to heart valve specialists (HVS) on AVR utilization. METHODS: Patients with severe aortic stenosis (AS) between 2015 and 2018, who met class I indication for intervention, were identified. Baseline data and process-related parameters were collected to analyze referral predictors and evaluate outcomes. RESULTS: Among 981 patients meeting criteria AVR, 790 patients (80.5%) were assessed by HVS within six months of index TTE. Factors linked to reduced referral included increasing age (OR: 0.95; 95% CI: 0.94-0.97; P < .001), unmarried status (OR: 0.59; 95% CI: 0.43-0.83; P = .002) and inpatient TTE (OR: 0.27; 95% CI: 0.19-0.38; P < .001). Conversely, higher hematocrit (OR: 1.13; 95% CI: 1.09-1.16; P < .001) and eGFR (OR: 1.01; 95% CI: 1.00-1.02; P = .003), mean aortic valve gradient (OR: 1.03; 95% CI: 1.01-1.04; P < .001) and preserved LVEF (OR: 1.59; 95% CI: 1.02-2.48; P = .04), were associated with increased referral likelihood. Moreover, patients assessed by HVS referral as a time-dependent covariate had a significantly lower two-year mortality risk than those who were not (aHR: 0.30; 95% CI: 0.23-0.39; P < .001). CONCLUSION: A substantial proportion of severe AS patients meeting indications for AVR are not evaluated by HVS and experience markedly increased mortality. Further research is warranted to assess the efficacy of care delivery mechanisms, such as e-consults, and telemedicine, to improve access to HVS expertise.

RESUMEN

OBJECTIVE: In patients with chronic kidney disease (CKD) undergoing transcatheter aortic valve replacement (TAVR), this study aims to elucidate (a) the bleeding risks associated with CKD, (b) the association between bleeding and subsequent mortality, and (c) the pattern of antithrombotic therapy prescribed. BACKGROUND: Patients with CKD have a higher risk of bleeding following TAVR. It is unclear whether this risk persists beyond the periprocedural period and whether it negatively impacts mortality. METHODS: A retrospective review was performed on patients who underwent TAVR at Massachusetts General Hospital from 2008 to 2017. CKD was defined as estimated glomerular filtration rate less than 60 ml/min/1.73 m2 . Primary endpoints up to 1-year following TAVR included bleeding, all-cause mortality, and ischemic stroke. Outcomes for patients with and without CKD were compared using log-rank test, and Cox regression with age, sex, and diabetes as covariates. Bleeding was treated as a time-varying covariate, and Cox proportional hazard regression was utilized to model mortality. RESULTS: Of the 773 patients analyzed, 466 (60.3%) had CKD. At 1 year, CKD patients had higher rates of bleeding (9.2 vs. 4.9%, adjusted hazard ratios [aHR] = 1.91, p = .032) and all-cause mortality (13.7 vs. 9.1%, aHR = 1.57, p = .049), but not stroke (3.9 vs. 1.6% aHR = 0.073, p = .094). Bleeding was associated with an increased risk of subsequent mortality (aHR = 2.65, 95% CI: 1.25-5.63, p = .01). There were no differences in the antithrombotic strategy following TAVR between CKD and non-CKD patients. CONCLUSION: CKD is associated with a higher risk of bleeding up to 1 year following TAVR. Long-term bleeding after TAVR is associated with increased subsequent mortality.

RESUMEN

OBJECTIVES: To investigate the prevalence, predictors and associations between guideline-directed medical therapy (GDMT) and clinical outcomes in acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI) from eight academic centers in the United States. BACKGROUND: Evidence for GDMT in patients with AMI comes from randomized controlled trials. The use of GDMT in clinical practice is unknown in this setting. METHODS: PROMETHEUS is a multicenter observational registry comprising 19,914 patients with acute coronary syndrome (ACS) undergoing PCI. Patients with AMI were divided into two groups based on the prescription of GDMT or not (non-GDMT) at discharge. GDMT was defined according to American College of Cardiology/American Heart Association (ACC/AHA) class I recommendations, specifically, dual antiplatelet therapy, statin and beta-blocker for all AMI patients, and additional ACEI/ARB in patients with left ventricular ejection fraction (LVEF) less than 40%, hypertension, diabetes mellitus (DM) or chronic kidney disease (CKD). The primary endpoint was major adverse cardiovascular events (MACE) defined as a composite of all-cause death, MI, stroke or unplanned target vessel revascularization (TVR) at 1 year. RESULTS: Out of 4,834 patients with AMI, 3,356 (69.4%) patients were discharged on GDMT. Patients receiving GDMT were more often younger and male. Compared with non-GDMT patients, GDMT patients had a significantly lower frequency of comorbidities. Predictors of greater GDMT prescription at discharge were ST-segment elevation myocardial infarction (STEMI), and increased body mass index (BMI), whereas hypertension, prior PCI, anemia and CKD were associated with less GDMT prescription. At 1 year, the use of GDMT was associated with a significantly lower incidence of MACE (13.7% vs. 22.5%; adjusted HR 0.68; 95%CI 0.58-0.80; P < 0.001), death (3.7% vs. 9.4%; adjusted HR 0.61; 95%CI 0.46-0.80; P < 0.001), and unplanned TVR (8.4% vs. 11.3%; adjusted HR 0.76; 95%CI 0.61-0.96; P = 0.020). However, there were no significant differences in the incidence of MI (4.3% vs. 7.0%; adjusted HR 0.75; 95%CI 0.56-1.01; P = 0.056), stroke (1.5% vs. 2.0%; adjusted HR 0.79; 95%CI 0.47-1.34; P = 0.384) between the two groups. CONCLUSION: In a contemporary practice setting in the United States, GDMT was utilized in just over two-thirds of AMI patients undergoing PCI. Predictors of GDMT prescription at discharge included STEMI, BMI and absence of hypertension, CKD, anemia or prior PCI. Use of GDMT was associated with significantly lower risk of 1-year MACE and mortality.

RESUMEN

We sought to investigate the utilization of prasugrel and its association with outcomes relative to clopidogrel in three typical subgroups of ACS in a real-world setting. Prasugrel is superior to clopidogrel for reducing risk of ischemic events in acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI), but is associated with an increased risk of bleeding complications. PROMETHEUS was a retrospective multicenter observational study of 19,913 ACS patients undergoing PCI from 8 centers in the United States between 2010 and 2013. Major adverse cardiovascular events (MACE) were defined as a composite of all-cause mortality, myocardial infarction, stroke or unplanned revascularization. The study cohort included 3285 (16.5%) patients with ST-segment elevation myocardial infarction (STEMI), 5412 (27.2%) patients with NSTEMI and 11,216 (56.3%) patients with unstable angina (UA). The frequency of prasugrel use at discharge was highest in STEMI and lowest in UA patients, 27.3% versus 22.2% versus 18.9% (p < 0.001). Use of prasugrel vs clopidogrel was associated with a lower rate of MACE in STEMI, NSTEMI, or UA at 1 year, but the differences were attenuated for all groups except for patients with UA (adjusted HR 0.81, 95% CI 0.69-0.94, p = 0.006) after propensity adjusted analysis. After adjustment, there was no difference in bleeding risk between prasugrel and clopidogrel for all groups at 1 year. STEMI patients were more likely to receive prasugrel compared to NSTEMI and UA patients. Prasugrel was associated with reduced adverse outcomes compared with clopidogrel in unadjusted analyses, findings that were largely attenuated upon adjustment and suggest preferential use of prasugrel in low vs high risk patients.

RESUMEN

AIMS: Recent studies suggest an association between cardiovascular disease (CVD) and cancer incidence/mortality, but the pathophysiological mechanisms underlying these associations are unclear. We aimed to examine biomarkers previously associated with CVD and study their association with incident cancer and cancer-related death in a prospective cohort study. METHODS AND RESULTS: We used a proteomic platform to measure 71 cardiovascular biomarkers among 5032 participants in the Framingham Heart Study who were free of cancer at baseline. We used multivariable-adjusted Cox models to examine the association of circulating protein biomarkers with risk of cancer incidence and mortality. To account for multiple testing, we set a 2-sided false discovery rate <0.05. Growth differentiation factor-15 (also known as macrophage inhibitory cytokine-1) was associated with increased risk of incident cancer [hazards ratio (HR) per 1 standard deviation increment 1.31, 95% CI 1.17-1.47], incident gastrointestinal cancer (HR 1.85, 95% CI 1.37-2.50), incident colorectal cancer (HR 1.94, 95% CI 1.29-2.91), and cancer-related death (HR 2.15, 95% CI 1.72-2.70). Stromal cell-derived factor-1 showed an inverse association with cancer-related death (HR 0.75, 95% CI 0.65-0.86). Fibroblast growth factor-23 showed an association with colorectal cancer (HR 1.55, 95% CI 1.20-2.00), and granulin was associated with haematologic cancer (HR 1.61, 95% CI 1.30-1.99). Other circulating biomarkers of inflammation, immune activation, metabolism, and fibrosis showed suggestive associations with future cancer diagnosis. CONCLUSION: We observed several significant associations between circulating CVD biomarkers and cancer, supporting the idea that shared biological pathways underlie both diseases. Further investigations of specific mechanisms that lead to both CVD and cancer are warranted.

RESUMEN

BACKGROUND: Despite the rapid growth of aortic valve replacement (AVR) for aortic stenosis (AS), limited data suggest symptomatic severe AS remains undertreated. OBJECTIVES: This study sought to investigate temporal trends in AVR utilization among patients with a clinical indication for AVR. METHODS: Patients with severe AS (aortic valve area <1 cm2) on transthoracic echocardiograms from 2000 to 2017 at 2 large academic medical centers were classified based on clinical guideline indications for AVR and divided into 4 AS subgroups: high gradient with normal left ventricular ejection fraction (LVEF) (HG-NEF), high gradient with low LVEF (HG-LEF), low gradient with normal LVEF (LG-NEF), and low gradient with low LVEF (LG-LEF). Utilization of AVR was examined and predictors identified. RESULTS: Of 10,795 patients, 6,150 (57%) had an indication or potential indication for AVR, of whom 2,977 (48%) received AVR. The frequency of AVR varied by AS subtype with LG groups less likely to receive an AVR (HG-NEF: 70%, HG-LEF: 53%, LG-NEF: 32%, LG-LEF: 38%, P < 0.001). AVR volumes grew over the 18-year study period but were paralleled by comparable growth in the number of patients with an indication for AVR. In patients with a Class I indication, younger age, coronary artery disease, smoking history, higher hematocrit, outpatient index transthoracic echocardiogram, and LVEF ≥0.5 were independently associated with an increased likelihood of receiving an AVR. AVR was associated with improved survival in each AS-subgroup. CONCLUSIONS: Over an 18-year period, the proportion of patients with an indication for AVR who did not receive AVR has remained substantial despite the rapid growth of AVR volumes.

RESUMEN

Background: Obesity and cardiometabolic dysfunction have been associated with cancer risk and severity. Underlying mechanisms remain unclear. Objectives: The aim of this study was to examine associations of obesity and related cardiometabolic traits with incident cancer. Methods: FHS (Framingham Heart Study) and PREVEND (Prevention of Renal and Vascular End-Stage Disease) study participants without prevalent cancer were studied, examining associations of obesity, body mass index (BMI), waist circumference, visceral adipose tissue (VAT) and subcutaneous adipose tissue depots, and C-reactive protein (CRP) with future cancer in Cox models. Results: Among 20,667 participants (mean age 50 years, 53% women), 2,619 cancer events were observed over a median follow-up duration of 15 years. Obesity was associated with increased risk for future gastrointestinal (HR: 1.30; 95% CI: 1.05-1.60), gynecologic (HR: 1.62; 95% CI: 1.08-2.45), and breast (HR: 1.32; 95% CI: 1.05-1.66) cancer and lower risk for lung cancer (HR: 0.62; 95% CI: 0.44-0.87). Similarly, waist circumference was associated with increased risk for overall, gastrointestinal, and gynecologic but not lung cancer. VAT but not subcutaneous adipose tissue was associated with risk for overall cancer (HR: 1.22; 95% CI: 1.05-1.43), lung cancer (HR: 1.92; 95% CI: 1.01-3.66), and melanoma (HR: 1.56; 95% CI: 1.02-2.38) independent of BMI. Last, higher CRP levels were associated with higher risk for overall, colorectal, and lung cancer (P < 0.05 for all). Conclusions: Obesity and abdominal adiposity are associated with future risk for specific cancers (eg, gastrointestinal, gynecologic). Although obesity was associated with lower risk for lung cancer, greater VAT and CRP were associated with higher lung cancer risk after adjusting for BMI.

RESUMEN

BACKGROUND: Unnecessary hospitalizations may pose the risk of iatrogenic complications, suboptimal patient experience, and increased cost. Administrative data lack granularity to understand the proportion and causes of hospitalizations preventable through optimizing care continuum (HPOCC). We aim to identify the incidence and causes of HPOCC through clinician-adjudicated chart review. METHODS: A retrospective review was performed for inpatient admissions from the emergency department (ED) over 1 week. Each admission was reviewed by a clinician to determine whether it is an HPOCC defined as not requiring inpatient care with the assumption of idealized outpatient care and social support. RESULTS: Of the 515 patients admitted from the ED, 31 (6.0%) patients were judged to have had an HPOCC. Causes of HPOCC include urgent diagnostics (9, 29.0%), unnecessary transfer from a long-term facility (7, 23.0%), needing IV therapy (5, 16.0%), benign incidental finding (5, 16.0%), diagnostic uncertainty in complex chronic illness (3, 10.0%), and lack of access to care for disposition (2, 6.0%). CONCLUSION: Hospitalizations preventable through optimizing care continuum account for about 1 in every 15 hospitalizations in an urban academic medical center. The need for urgent diagnostics accounts for a plurality of HPOCC and could be an important target for quality improvement.

RESUMEN

BACKGROUND: Women undergoing percutaneous coronary intervention (PCI) are at higher risk for bleeding and vascular complications than men. Multiple approaches have been utilized to reduce bleeding in the modern era of PCI, including radial access, reduced GP IIb/IIIa inhibitor use, increased vascular closure device use, smaller sheath size and novel antithrombotic regimens. Nevertheless, few studies have assessed the impact of these techniques on the gap between men and women for such complications following PCI. We sought to quantify bleeding and vascular complications over time between men and women. METHODS: We queried The Dartmouth Dynamic Registry for consecutive PCI's performed between January 2003 and June 2016. Demographic information, procedural characteristics, and in-hospital outcomes were collected and compared between men and women over the years. RESULTS: We reviewed 15,284 PCI cases, of which 4384 (29%) were performed in women. Radial access increased from none in 2003 to nearly 40% in 2016. Use of GP IIb/IIIa and femoral access decreased substantially over the same time. Bleeding and vascular complication rates decreased significantly in women (13.2% to 3%; 6.5% to 0.8%, respectively) and men (3.5% to 0.7%, 3.4% to 0.7%, respectively). The overall bleeding and vascular complication rates decreased more for women than men, narrowing the gender gap. CONCLUSIONS: The incidence of bleeding and vascular complications fell between 2003 and 2016 in both men and women. Vascular complications have become less common over time, and based on our analysis, there was no longer any difference between the sexes for this outcome. Bleeding following PCI has decreased in both sexes over time; however, women continue to bleed more than men.

RESUMEN

BACKGROUND: The extent to which co-occurrence of cardiovascular disease (CVD) and cancer is due to shared risk factors or other mechanisms is unknown. OBJECTIVES: We investigated the association of standard CVD risk factors, CVD biomarkers, preexisting CVD, and ideal CV health metrics with the development of future cancer. METHODS: We prospectively followed Framingham Heart Study and PREVEND participants free of cancer at baseline, and ascertained histology-proven cancer. We studied the association of baseline CV risk factors, 10-year atherosclerotic CVD risk score, established CVD biomarkers, prevalent CVD, and AHA Life's Simple 7 CV health score with incident cancer using multivariable Cox models. Analyses of interim CVD events with incident cancer used time-dependent covariates. RESULTS: Among 20,305 participants (mean age 50 ± 14 years, 54% women), 2,548 incident cancer cases occurred over a median follow-up of 15.0 (13.3-15.0) surveillance years. Traditional CVD risk factors including age, sex, and smoking status were independently associated with cancer (P <0.001 for all). Estimated 10-year atherosclerotic CVD risk was also associated with future cancer (HR 1.16 per 5% increase in risk, 95% CI 1.14-1.17, P<0.001). We found that natriuretic peptides (NP) (tertile 3 vs 1: HR 1.40, 95% CI 1.03-1.91, p=0.035) was associated with incident cancer, but not high sensitivity troponin (hs-cTn) (p=0.47). Prevalent CVD and the development of interim CV events were not associated with higher risk of subsequent cancer. However, ideal CV health was associated with lower future cancer risk (HR 0.95 per 1-point increase in AHA health score, 95% CI 0.92-0.99, p=0.009). CONCLUSIONS: CVD risk as captured by traditional CVD risk factors, 10-year atherosclerotic CVD risk score, and NP concentrations are associated with increased risk of future cancer. Conversely, a heart healthy lifestyle is associated with a reduced risk of future cancer. Our data suggest that the association between CVD and future cancer is attributable to shared risk factors.

RESUMEN

BACKGROUND: Very elderly patients (age ≥ 85 years) are a rapidly increasing segment of the population. As a group, they experience high rates of in-hospital mortality and bleeding complications following percutaneous coronary intervention (PCI). However, the relationship between bleeding and mortality in the very elderly is unknown. METHODS: Retrospective review was performed on 17,378 consecutive PCI procedures from 2000 to 2015 at Dartmouth-Hitchcock Medical Center. Incidence of bleeding during the index PCI admission (bleeding requiring transfusion, access site hematoma > 5 cm, pseudoaneurysm, and retroperitoneal bleed) and in-hospital mortality were reported for four age groups (< 65 years, 65-74 years, 75-84 years, and ≥ 85 years). The mortality of patients who suffered bleeding complications and those who did not was calculated and multivariate analysis was performed for in-hospital mortality. Lastly, known predictors of bleeding were compared between patients age < 85 years and age ≥ 85 years. RESULTS: Of 17,378 patients studied, 1019 (5.9%) experienced bleeding and 369 (2.1%) died in-hospital following PCI. Incidence of bleeding and in-hospital mortality increased monotonically with increasing age (mortality: 0.94%, 2.27%, 4.24% and 4.58%; bleeding: 3.96%, 6.62%, 10.68% and 13.99% for ages < 65, 65-74, 75-84 and ≥ 85 years, respectively). On multivariate analysis, bleeding was associated with increased mortality for all age groups except patients age ≥ 85 years [odds ratio (95% CI): age < 65 years, 3.65 (1.99-6.74); age 65-74 years, 2.83 (1.62-4.94); age 75-84 years, 3.86 (2.56-5.82), age ≥ 85 years: 1.39 (0.49-3.95)]. CONCLUSIONS: Bleeding and mortality following PCI increase with increasing age. For the very elderly, despite high rates of bleeding, bleeding is no longer predictive of in-hospital mortality following PCI.

RESUMEN

BACKGROUND: Patients with chronic kidney disease (CKD) experience high rates of ischemic and bleeding events after percutaneous coronary intervention (PCI), complicating decisions surrounding dual antiplatelet therapy (DAPT). This study aims to determine the pattern and impact of various modes of DAPT cessation for patients with CKD undergoing PCI. METHODS AND RESULTS: Patients from the PARIS registry (Patterns of Non-Adherence to Anti-Platelet Regimens in Stented Patients) were grouped based on the presence of CKD defined as creatinine clearance <60 mL/min. After index PCI, time and mode of DAPT cessation (discontinuation, interruption, and disruption) and clinical outcomes (major adverse cardiac events, stent thrombosis, myocardial infarction, and major bleeding [Bleeding Academic Research Consortium type 3 or 5]) were reported. Over 2 years, patients with CKD (n=839) had higher adjusted risks for death (hazard ratio, 3.16; 95% confidence interval, 2.26-4.41), myocardial infarction (hazard ratio, 2.43; 95% confidence interval, 1.65-3.57), and major bleeding (hazard ratio, 2.21; 95% confidence interval, 1.53-3.19) compared with patients without CKD (n=3745). Rates of DAPT discontinuation within the first year after PCI and disruption were significantly higher for patients with CKD. However, DAPT interruption occurred with equal frequency. Associations between DAPT cessation mode and subsequent risk were not modified by CKD status. Findings were unchanged after propensity matching. CONCLUSIONS: Patients with CKD display high and comparable risks for both ischemic and bleeding events after PCI. Physicians are more likely to discontinue DAPT within the first year after PCI among patients with CKD, likely reflecting clinical preferences to avoid bleeding. Risks after DAPT cessation, irrespective of underlying mode, are not modified by the presence or absence of CKD.

RESUMEN

The role of classroom learning in medical education is rapidly changing. To promote active learning and reduce student stress, medical schools have adopted policies such as pass/fail curriculums and recorded lectures. These policies along with the rising importance of the USMLE (United States Medical Licensing Examination) exams have made asynchronous learning popular to the detriment of classroom learning. In contrast to this model, modern day business schools employ mandatory large group classes with assigned seating and cold-calling. Despite similar student demographics, medical and business schools have adopted vastly different approaches to the classroom. When examining the classroom dynamic at business schools with mandatory classes, it is evident that there's an abundance of engaging discourse and peer learning objectives that medical schools share. Mandatory classes leverage the network effect just like social media forums such as Facebook and Twitter. That is, the value of a classroom discussion increases when more students are present to participate. At a time when students are savvy consumers of knowledge, the classroom is competing against an explosion of study aids dedicated to USMLE preparation. Certainly, the purpose of medical school is not solely about the efficient transfer of knowledge - but to train authentic, competent, and complete physicians. To accomplish this, we must promote the inimitable and deeply personal interactions amongst faculty and students. When viewed through this lens, mandatory classes might just be a way for medical schools to leverage their competitive advantage in educating the complete physician.

RESUMEN

Aim: To describe the presentation and management of a urinoma developing as a complication of laparoscopic cryoablation of a Bosniak III renal cyst. Case: A 74-year-old woman presented with acute onset of severe left lower abdominal pain 1 day after a laparoscopic cryoablation of a 3 cm multilobular left cystic renal mass. CT revealed a perinephric fluid collection adjacent to the lower pole of the left kidney with active urinary extravasation seen on retrograde pyelogram, confirming the presence of an urinoma. A retrograde ureteral stent was placed with complete resolution of symptoms and the patient was discharged on the first postoperative day. Follow-up CT scans 2 weeks and 2 months after the procedure showed significant reduction of urinoma size, and retrograde pyelogram 5 months after showed resolution of urinoma. Conclusion: Although often discussed as a possible complication, to our knowledge there are no published case reports in the literature regarding the formation of a urinoma after laparoscopic cryoablation. Furthermore, no data exist on the management of a urinoma after laparoscopic cryoablation. We propose that ureteral stenting is a reasonable approach to the management of this condition.

RESUMEN

BACKGROUND: Patients with inflammatory bowel disease (IBD) require regular follow-up to manage their care, which requires significant amount of time and out-of-pocket costs. Telemedicine in the form of video virtual visits could serve as an alternative to in-office visits. The aim of this project was to understand if telemedicine can provide high value care (defined as quality/cost) to outpatients with IBD. METHODS: Patients who participated in the IBD telemedicine clinic in the second half of 2015 were included. Patient-reported survey data before and after the virtual visit were collected. A retrospective review was performed on the study cohort for quality outcome measures a year before and after starting the telemedicine clinic. Outcomes were analyzed using simple descriptive statistics. Differences in quality outcomes were compared using odds ratios. RESULTS: Forty-eight patients were included in the analysis. Most patients travel more than 25 miles each way, take half a day off, and on average incur an additional out-of-pocket cost of $62 for an in-office visit. Most patients (98%) agreed that there was enough time spent with their physician, 91% agreed that they felt like the physician understood their disease state, and 78% reported that they clearly understood the follow-up plan after the visit. Analysis of quality outcome measures did not show any drop in the overall quality of care, after initiating the telemedicine program. CONCLUSIONS: Telemedicine offers a low cost and convenient alternative for patients with IBD without compromising quality of care.
