RESUMEN

BACKGROUND: Systemic thrombolysis (ST) may not be ideal for many patients with acute pulmonary embolism (PE) due to bleeding risk. In this analysis, we evaluated the safety and effectiveness of mechanical thrombectomy (MT) as an alternative to ST for acute PE. METHODS: Patients aged ≥18 years who underwent MT and/or ST for PE were identified from the National Inpatient Sample database from 2016 to 2017. Patients who underwent catheter-directed thrombolysis were excluded. We compared in-hospital outcomes of both groups in this retrospective study. RESULTS: Of 16 890 patients who received an intervention for acute PE, 1380 (8.2%) received MT and 15 510 (91.8%) received ST. There was no difference in age between both groups. In-hospital mortality was significantly lower in patients who received MT than that in those who received ST (11.9% vs 20.6%, odds ratio [OR]: 0.52, 95% confidence interval [CI]: 0.29-0.93, p=0.028). There was no statistically significant difference in terms of periprocedural bleeding, intracranial hemorrhage, and acute kidney injury between the 2 groups (p≥0.608 for all). Patients who received MT had a higher rate of respiratory complications (19.0% vs 11.6%, OR: 1.79, 95% CI: 1.06-3.03, p=0.030) and discharge to an outside facility (34.1% vs 19.2%, OR: 2.18, 95% CI: 1.41-3.37, p<0.001) than those who received ST. CONCLUSION: Mortality was significantly lower with MT than that with ST, but larger randomized studies are needed to validate this. The use of MT should be individualized on the basis of the patients' clinical presentation, risk profile, and local resources. CLINICAL IMPACT: In this study, we utilized the National Inpatient Sample database to study the in-hospital outcomes of pulmonary embolism patients who underwent mechanical thrombectomy compared to those who underwent systemic thrombolysis. We found that the patients who were diagnosed with pulmonary embolism and underwent mechanical thrombectomy had significantly lower mortality compared to those who were treated using systemic thrombolysis. This study was the first of its kind, utilizing the national inpatient sample database for evaluation of mechanical thrombectomy in comparison with the standard of care. These result would direct further randomized controlled trials for better evaluation of the utilization of mechanical thrombectomy in the correct clinical context. Furthermore, our study demonstrated comparable peri-operative complications between the mechanical thrombectomy group and the systemic thrombolysis group. These results would direct clinicians to consider mechanical thrombectomy if clinically indicated given the promising results.

RESUMEN

BACKGROUND: Transcatheter mitral valve repair (TMVR) is a treatment option for patients with 3+ or greater mitral regurgitation who cannot undergo mitral valve surgery. Outcomes in patients with chronic kidney disease (CKD) and end stage renal disease (ESRD) are unclear. We sought to evaluate the TMVR in-hospital outcomes, readmission rates and its impact on kidney function. METHODS: Data from 2016 National Readmission Database was used to obtain all patients who underwent TMVR. Patients were classified by their CKD status: no CKD, CKD, or ESRD. The primary outcomes were: in-hospital mortality, 30- and 90-day readmission rate, and change in CKD status on readmission. Multivariable logistic regression analysis was used to assess in-hospital, readmission outcomes and kidney function stage. RESULTS: A total of 4,645 patients were assessed (mean age 78.5 ± 10.3 years). In-hospital mortality was higher in patients with CKD (4.0%, odds ratio [OR]:2.01 [95% CI, confidence interval: 1.27-3.18]) and ESRD (6.6%, OR: 6.38 [95% CI: 1.49-27.36]) compared with non-CKD (2.4%). 30-day readmission rate was higher in ESRD versus non-CKD patients (17.8% vs. 10.4%, OR: 2.24 [95% CI: 1.30-3.87]) as was 90-day readmission (41.2% vs. 21% OR: 2.51 [95% CI:1.70-3.72]). Kidney function improved in 25% of patients with CKD stage 3 and in 50% with CKD stage 4-5 at 30-and 90-day readmission. Incidence of AKI, major bleeding, and respiratory failure were higher in CKD group. CONCLUSIONS: Patients with CKD and ESRD have worse outcomes and higher readmission rate after TMVR. In patients who were readmitted after TMVR, renal function improved in some patients, suggesting that TMVR could potentially improve CKD stage.

RESUMEN

BACKGROUND: Pulmonary vein isolation (PVI) is the cornerstone of atrial fibrillation (AF) ablation but the recurrence rate remains relatively high in persistent patients with AF. Therefore, posterior wall isolation (PWI) in addition to PVI has been proposed to increase freedom from AF. OBJECTIVE: To evaluate the success of adjunctive PWI in persistent AF. METHODS: We searched electronic database using specific terms. The primary outcomes are recurrence rate of AF and recurrence of atrial arrhythmias. The secondary outcomes were atrial flutter/tachycardia (AFL/AT), procedure time, fluoroscopy time, and procedure related complications. Estimated risk ratios (RRs) and 95% confidence intervals (CIs) were evaluated. RESULTS: Six studies were included (1334 patients with persistent AF). Adjunctive PWI resulted in a significant reduction in the recurrence rate of AF compared with patients who had PVI only (19.8% vs 29.1%; RR, 0.64; 95% CI, 0.42-0.97; P < .04; I2 = 76%). There was a significant reduction in the recurrence rate of all atrial arrhythmia (30.8% vs 41.1%; RR, 0.75; 95% CI, 0.60-0.94; P < .01; I2 = 60%). Compared with PVI only, adjunctive PWI did not increase the rate of AFL or AT (11.6% vs 13.9%; RR, 0.85; 95% CI, 0.54-1.32; P < .46; I2 = 47%) or the rate of procedure related complications (4.6% vs 3.6%; RR, 1.25; 95% CI, 0.72-2.17; P < .44; I2 = 0%). CONCLUSION: In patients with persistent AF, adjunctive PWI was associated with decreased recurrence of AF and atrial arrhythmias compared with PVI alone without an increased risk of AFL or AT or procedure related complications.

RESUMEN

Newer generation drug eluting stents (DES) and pharmacotherapy have decreased thrombotic events post-percutaneous coronary intervention (PCI). There is lack of wide-ranging safety and efficacy evaluation in both stable ischemic heart disease and acute coronary syndrome in short-term (3-6 months) versus Standard-term (12 months) dual antiplatelet therapy (DAPT). We searched electronic databases using specific terms to identify randomized control trials comparing different durations of DAPT after PCI with DES. The outcomes of interest included all-cause mortality, myocardial infarction, stent thrombosis, major bleeding, target lesion and vessel revascularization, and stroke at follow-up duration ≥12 months post index PCI. Studies that compared DAPT <3 months or DAPT ≥12 months were excluded. Thirteen randomized control trials (n = 31,831) were included; 8401 patients received DAPT for 3 months and 7482 patients received DAPT in the 6 months group. Major bleeding rate was lower in the short-term (3-6 months) versus Standard-term (12 months) group (risk ratio 0.66; 95% confidence interval, 0.52-0.84, P < 0.05). Repeat revascularization rate was higher in the short-term (3-6 months) versus Standard-term (12 months) (risk ratio 1.17; 95% confidence interval, 1.01-1.36, P < 0.05) of DAPT duration after PCI with DES. No difference in other outcomes were observed when comparing short versus standard duration of DAPT in both stable ischemic heart disease and acute coronary syndrome.

RESUMEN

BACKGROUND: Subcutaneous implantable cardioverter defibrillators (S-ICDs) have gained increasing popularity because of certain advantages over transvenous ICDs. However, while conventional ICDs require a single surgical incision to implant, S-ICDS need two or three incisions, making them less appealing. OBJECTIVE: This study sought out to investigate the feasibility of using a single-incision technique to implant S-ICDs. METHODS: Patients qualifying for S-ICDs were considered for a single incision. A single incision is performed by making a left inframammary incision and then the subcutaneous tissue is dissected medially toward the lower sternum. Two sutures are placed in the fascia in the xiphoid area to anchor the lead and a tunneling tool is used to dissect the tissue to place the lead parallel to the sternum. Then subcutaneous tissues are dissected down the lateral chest wall over the muscle fascia to create the pulse generator pocket in the vicinity of the fifth and sixth intercostal spaces and near the mid-axillary line. RESULTS: Eleven patients (six males and five females) successfully underwent S-ICD implantation with a single incision without acute complications (64% for primary prevention). The mean age is 47.4 ± 15.8 years. There were no lead dislodgements, inappropriate shocks, or any other issues during a median follow-up of 10 months (interquartile range 5-17). One patient had a successful appropriate shock for ventricular fibrillation about one year after device implant. CONCLUSIONS: A single incision for subcutaneous ICDs is feasible and safe in our early experience.

RESUMEN

Coronary chronic total occlusion (CTO) is common in patients with multivessel coronary artery disease. Percutaneous coronary artery (PCI) interventions have shown favorable outcomes in patients with CTO. Nevertheless, the data regarding the utilization of mechanical circulatory support in CTO PCIs is not well established. We sought to investigate the trends in utilization and periprocedural complications in this population. Using the National Inpatient Sample database from 2011 to 2019, we identified patients diagnosed with CTO who underwent PCI. We investigated the presence of a linear trend in the utilization of mechanical circulatory support (MCS) during those procedures and the associated periprocedural complications using the Cochran-Armitage method. A total of 208,123 patients who were diagnosed with CTO and underwent PCI from 2011 to 2019, of which in 6,319 patients MCS was used during the procedure. Patients in the MCS group were older (67.4 vs 66.4 years), less likely to be women (24.0% vs 26.4%), and equally likely to be African-American (9.4% vs 8.8%) with a higher burden of co-morbidities in terms of coronary artery disease, congestive heart failure, and atrial fibrillation (p <0.001 for all). Using the Cochrane-Armitage method, we found a statistically significant linear uptrend in the utilization of MCS from 269 (1.4%) to 990 cases (7.0%) from 2011 to 2019. Using multivariable logistic regression, female gender, renal failure, alcohol abuse, coagulopathy, and fluid and electrolyte disorders were identified as independent predictors of mortality in CTO PCI procedures assisted with MCS (p ≤0.007). In conclusion, the utilization of MCS in CTO PCI procedures has been increasing over the years. Female gender and renal failure are independently associated with a higher mortality risk.

RESUMEN

Sodium-glucose cotransporter-2 inhibitors (SGLT2-Is) have emerged as standard therapy for heart failure. We aim to assess the safety of SGLT2-Is in patients with a high risk of cardiovascular disease. Areas covered: An electronic database search was conducted for randomized control trials comparing SGLT2-Is to placebo in patients with a high risk of cardiac disease or heart failure. Data were pooled for outcomes using random-effect models. The odds ratio (OR) and 95% confidence interval (CI) were used to compare eight safety outcomes between the two groups. The analysis included ten studies with 71 553 participants, among whom 39 053 received SGLT2-Is; 28 809 were male and 15 655 were female (mean age, 65.2 years). The mean follow-up period was 2.3 years with the range being 0.8-4.2 years. The SGLT2-Is group had a significant reduction in AKI (OR = 0.8;95% CI 0.74-0.90) and serious adverse effects (OR = 0.9; 95% CI 0.83-0.96) as compared to placebo. No difference was found in fracture (OR = 1.1; 95% CI 0.91-1.24), amputation (OR = 1.1; 95% CI 1.00-1.29), hypoglycemia (OR 0.98;95% CI 0.83-1.15), and UTI (OR = 1.1; 95% CI 1.00-1.22). In contrast, DKA (OR = 2.4; 95% CI 1.65-3.60) and volume depletion (OR = 1.2; 95% CI 1.07-1.41) were higher in SGLT2-Is group. Expert opinion/commentary: The benefits of SLGT2-Is outweigh the risk of adverse events. They may reduce the risk of AKI but are associated with an increased risk of DKA and volume depletion. Further studies are warranted to monitor a wider range of safety outcomes of SGLT2-Is.

RESUMEN

Importance: The cardiovascular outcome in selected populations when sodium-glucose cotransporter 2 inhibitors (SGLT2-Is) are emerging as standard therapy is not clearly understood. It is important to learn the magnitude of cardiovascular benefit using SGLT2-Is across the select subgroups that include both sexes and multiple age and racial and ethnic groups. Objectives: To evaluate the association between use of SGLT2-Is and cardiovascular benefits in a prespecified group in a larger sample size using data obtained from randomized clinical trials. Data Sources: Search of electronic databases PubMed, Google Scholar, Web of Science, and Cochrane from inception to January 10, 2021, with additional studies identified through conference papers and meeting presentations, ClinicalTrials.gov, and reference lists of published studies. Study Selection: Placebo-controlled randomized clinical trials in which participants had atherosclerotic cardiovascular disease (ASCVD) or risk factors for ASCVD, diabetes, or heart failure and which reported the primary outcome were included in this study. Multicenter observational and nonobservational studies and those with different outcomes of interest were excluded. Data Extraction and Synthesis: Medical Subject Heading search terms included SGLT2-I and multiple cardiovascular outcomes in different combinations. The study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. The analysis of all outcomes was performed using a Mantel-Haenszel equation and the random-effects model. Main Outcomes and Measures: Six efficacy outcomes of SGLT2-I use (cardiovascular death and hospitalization for heart failure [HHF] as the primary outcome and major adverse cardiovascular event, HHF, cardiovascular death, acute myocardial infarction, and all-cause mortality as secondary outcomes), were evaluated. Subgroup analysis was performed for the primary outcome of cardiovascular death or HHF. Odds ratios (ORs) and 95% CIs were used to compare 2 interventions. Results: Ten studies with 71 553 participants were included, among whom 39 053 received SGLT2-Is; among studies that reported these data, 28 809 were men and 15 655 were women (mean age, 65.2 [range, 61.9-70.0] years). Race and ethnicity were defined in the original trials and were categorized as Asian, Black, or other (6900 participants) and White (26 646 participants) for the purposes of this analysis (the category "other" was not specified consistently). In terms of age, 16 793 were younger than 65 years and 17 087 were 65 years or older. At a mean follow-up 2.3 (range, 0.8-4.2) years, the SGLT2-I group favored reduction in primary outcome (3165 of 39 053 [8.10%] vs 3756 of 32 500 [11.56%]; OR, 0.67 [95% CI, 0.55-0.80]; P < .001). No difference was noted in the rate of acute myocardial infarction compared with the placebo group (1256 of 26 931 [4.66%] vs 958 of 20 373 [4.70%]; OR, 0.95 [95% CI, 0.87-1.03]; P = .22). Subgroup analysis favored SGLT2-I use for the primary outcome in both sexes, age groups, and racial and ethnic groups. Conclusions and Relevance: This meta-analysis supports that SGLT2-Is have emerged as an effective class of drugs for improving cardiovascular morbidity and mortality in selected patients. Sodium-glucose cotransporter 2 inhibitors were not associated with reduced risk of acute myocardial infarction. Future long-term prospective studies are warranted to understand the long-term cardiovascular benefits.

RESUMEN

AIMS: Data on cardiogenic shock (CS) in autoimmune diseases (AID) is limited. Our study aims to evaluate in-hospital outcomes of CS in hospitalized patients with underlying AID compared with patients without AID. METHODS: The National Inpatient Sample (NIS) database years 2011-17 was used to identify hospitalizations for CS. We retrospectively compared in-hospital outcomes of CS in patients with underlying AID versus non-AID. RESULTS: Of 863,239 patients diagnosed with CS, 23,127 (2.7%) had underlying AID. The AID population was older with more women and African American patients (P < 0.001 for all). There was a significant increase in in-hospital mortality in patients with AID vs non-AID that persisted after adjustment for demographics, comorbidities, insurance, socioeconomic status and hospital characteristics (38.3% vs 36.3%, aOR 1.06; 95% CI: 1.02-1.09, P = 0.001). Patients with AID had a lower rate of respiratory complications (11.5% vs 13.1%), acute stroke (6.0% vs 6.8%), use of mechanical circulatory support (12.0% vs 14.5%) and discharge to an outside facility (29.1% vs 28.8%) (P ≤ 0.001 for all). Using multivariable logistic regression, we identified female gender, Native American ethnicity, heart failure, coagulopathy, pulmonary circulation disorders, metastatic cancer, and fluid and electrolytes disorders as independent predictors of mortality in patients with AID who were diagnosed with CS. CONCLUSION: Patients with AID hospitalized with CS have increased mortality which may be related to their underlying disease process and lack of effective disease-directed therapy for CS related to AID.

RESUMEN

OBJECTIVES: To demonstrate a magnitude of the cardiovascular benefits, concomitantly analyzing the safety outcomes of sodium-glucose cotransporter 2 inhibitor (SGLT2-I) comprehensively, as a class effect in a larger sample size combined from recent randomized control trials. METHODS: We searched electronic databases using specific terms and evaluated 6 efficacy and 10 safety outcomes. Odds ratios (ORs) and 95% confidence interval (CI) were used to compare two interventions. RESULTS: Five studies (n = 41 267) were included, among which 23 539 received SGLT2-I. The SGLT2-I group favored reduction in major adverse cardiovascular events (OR, 0.78; 95% CI, 0.62-0.98; P = 0.03), cardiovascular death (CVD) or heart failure hospitalization (OR, 0.60; 95% CI, 0.46-0.80; P = 0.0004), rate of hospitalization for heart failure (OR, 0.56; 95% CI, 0.44-0.72; P < 0.00001), CVD (OR, 0.68; 95% CI, 0.50-0.93; P = 0.01), all-cause mortality (OR, 0.67; 95% CI, 0.48-0.93; P = 0.02) and myocardial infarction (OR, 0.79; 95% CI, 0.64-0.99; P = 0.04) when compared to the placebo group. Safety analysis showed higher diabetic ketoacidosis (DKA) rate in SGLT2-I group (OR, 2.33; 95% CI, 1.40-3.90; P = 0.001); in contrast, major hypoglycemic events were significantly lower (OR, 0.79; 95% CI, 0.73-0.87; P < 0.00001). AKI was significantly higher in the placebo group (OR, 0.76; 95% CI, 0.65-0.88; P = 0.0004). There were no statistically significant effects on other outcomes. CONCLUSION: In selected high-risk patients of cardiovascular disease, the SGLT2-I is a potential effective class of drugs for improving cardiovascular outcomes and all-cause mortality without an increased risk of all other major complications except DKA on this meta-analysis.

RESUMEN

BACKGROUND: Atrial fibrillation (AF) is the most common cardiac arrhythmia encountered in clinical practice. However, the outcomes associated with AF in hospitalized patients with liver cirrhosis are unknown. AIM: To determine the outcomes of hospitalized patients with liver cirrhosis and AF. METHODS: In this study, we examined morbidity and mortality of patients with concomitant AF and liver cirrhosis from the National Inpatient Sample database, the largest publicly available inpatient healthcare database in the United States. RESULTS: A total of 696937 patients with liver cirrhosis were included, 45745 of whom had concomitant AF (6.6%). Liver cirrhosis patients with AF had higher rates of in-hospital mortality (12.6% vs 10.3%, P < 0.001), clinical stroke (1.6% vs 1.1%, P < 0.001), and acute kidney injury (28.2% vs 25.1%, P < 0.001), and less gastrointestinal bleeding (4.4% vs 5.1%, P < 0.001) and blood transfusion (22.5% vs 23.8%, P < 0.001) compared with those who did not have the arrhythmia. In addition, they had a longer length of stay (8 ± 10 d vs 7 ± 8 d, P < 0.001) and higher hospitalization costs (20720 ± 33210 $ vs 16272 ± 24166 $, P < 0.001). CONCLUSION: In subjects with liver cirrhosis, AF is associated with higher rates of inpatient mortality, stroke, and acute kidney injury compared to those who do not have the cardiac arrhythmia.

RESUMEN

BACKGROUND: In patients with ST elevation myocardial infarction (STEMI), primary percutaneous coronary intervention (PCI) of the culprit vessel is the preferred treatment option. For patients with multivessel disease, the benefit of revascularization of the non-culprit artery is not well known. This meta-analysis aims to assess the efficacy and safety of complete versus culprit vessel only revascularization. METHODS: Randomized control trials (RCT) that compared head-to-head complete versus culprit-vessel only revascularization in STEMI patients and reported main outcomes of interest such as mortality, myocardial infarction, and revascularization, were included in this meta-analysis. RESULTS: We found ten RCTs satisfying our inclusion criteria. Data was extracted and used to estimate the risk ratio (RR) and 95% confidence interval (CI) for dichotomous variables. Our study included 7030 patients (3426 complete revascularization, and 3604 culprit-only revascularization). Complete revascularization (CR) (both immediate and staged) significantly reduced the risk of MACE compared with culprit only (CO) revascularization (10.7% vs 20.1%, RR 0.53; 95% CI 0.43 to 0.64; P < 0.0001), reinfarction (5.0% vs 6.9%, RR 0.69; 95 CI 0.51 to 0.93; P < 0.01), and revascularization (4.2% vs 12.7%, RR 0.37; 95 CI 0.26 to 0.54; P < 0.0001). Our analysis did not find any significant difference in all-cause mortality between CR and CO (4.6% vs 5.0%, RR 0.89; 95 CI 0.72 to 0.1.10; P = 0.27). CONCLUSION: In conclusion, complete revascularization was associated with a significant reduction in major adverse cardiovascular events, revascularization and reinfarction.

RESUMEN

BACKGROUND: Transaortic flow, maximum velocity (V max), mean gradient (MG), left ventricular ejection fraction (LVEF), Aortic valve area (AVA) and dimensional index (DI) are important determinants of prognosis in patients with severe aortic stenosis. The specific role of these echocardiography-derived values in predicting prognosis of severe aortic stenosis patients undergoing Transcatheter aortic valve replacement (TAVR) is less defined. METHODS: We identified all severe AS patients who underwent TAVR between 01/2012 and 6/2016. Baseline characteristics, clinical, procedural and one year follow-up data were obtained. Hierarchical logistic regression was used to assess predictors of 1-year mortality after TAVR. Normal flow (NF) was defined as having stroke volume index (SVI) of ≥35 ml/m2; while low Flow (LF) was defined as SVI < 35 ml/m2. High gradient (HG) was defined as mean gradient of ≥40 mmHg; while low gradient (LG) was defined as <40 mmHg. RESULTS: A total of 399 patients were analyzed. There were no significant differences in baseline characteristics. LVEF less than 35% was associated with higher rate of 1-year mortality (17.6% LVEF <35% vs. 8.9% LVEF≥35%; RR = 2.19; CI 1.05 to 4.54; P = 0.03). There was no difference in 1-year mortality outcomes after TAVR in relation to: Mean Gradient MG, transaortic flow/Stroke Volume Index SVI, DI, V max or AVA. CONCLUSION: Low LVEF <35% remains the strongest parameter associated with 1 year mortality after TAVR.

RESUMEN

Antiphospholipid syndrome is an autoimmune disorder that presents clinically with venous and/or arterial thrombosis and can affect any organ. Coronary artery involvement and left ventricular thrombus are rare presentations. We report the case of a 23-year-old male smoker with a strong family history of premature coronary artery disease who presented with acute anterolateral ST elevation myocardial infarction and large left ventricular thrombus. He was treated with primary percutaneous coronary intervention with thrombectomy without stenting. He was later diagnosed with antiphospholipid syndrome.

RESUMEN

OBJECTIVES: Patients with cirrhosis have increased bleeding risk due to coagulopathy and platelet sequestration, as well as inherent cardiovascular risk. We aim to assess the impact of cirrhosis on the revascularization rates and in-hospital outcomes in patients with acute myocardial infarction (AMI). METHODS: We queried the National Inpatient Sample Database from 2010 to 2014 and identified hospitalizations with a primary diagnosis of AMI (n = 612,547); of these, a total of 3135 patients had a concomitant diagnosis of cirrhosis. We compared clinical outcomes between patients with cirrhosis and a propensity-score matched cohort without cirrhosis (n = 3086). RESULTS: Patients with cirrhosis had a lower rate of ST-elevation MI (18.9% vs 26.7% in the cohort with no cirrhosis; P<.001), a lower rate of coronary angiography (51.4% vs 63.9% in the cohort with no cirrhosis; P<.001), and lower rates of revascularization by percutaneous coronary intervention (PCI) (28.7% vs 39.2% in the cohort with no cirrhosis; P<.001) or coronary artery bypass grafting (6.0% vs 12.9% in the cohort with no cirrhosis; P<.001). Gastrointestinal and postprocedural hemorrhage was more common in patients with cirrhosis (12.3% vs 7.1% in the cohort with no cirrhosis; P<.001), regardless of revascularization status, and cirrhosis patients also had a higher in-hospital mortality rate (8.7% vs 6.9% in the cohort with no cirrhosis; P<.01). PCI was independently associated with lower mortality in patients with cirrhosis (odds ratio, 0.57; 95% confidence interval, 0.33-0.98; P=.04). CONCLUSION: Patients with cirrhosis presenting with AMI were highly selected to undergo coronary angiography and subsequent revascularization, and had higher mortality than those without cirrhosis. However, PCI was independently associated with lower mortality in patients with cirrhosis, although to less effect than non-cirrhotics, perhaps due to higher bleeding rates.

RESUMEN

The measurement of cardiac troponin, released from injured cardiomyocytes, is of paramount importance in the diagnosis of acute myocardial infarction. Elevated troponin can be encountered, however, in patients with cardiomyopathy, significant cardiac arrhythmias, vasculitis, right-sided heart strain, critical systemic illnesses, stroke, drug toxicity (such as Adriamycin), poisons (such as snake venoms), renal failure, seizure, and rhabdomyolysis. If the clinical picture is not consistent with any of these causes, a false-positive result should be considered. We herein describe a 94-year-old man with a prior history of coronary artery disease who presented with altered mental status and was found to have a persistently high troponin level resulting in three admissions to the coronary care unit for various noncardiac complaints. Because of discordance between clinical and laboratory data, immunological interference due to heterophile antibodies in the locally used assay (AccuTnI+3, Beckman Coulter) was suspected. The same serum sample tested on a different assay (Elecsys Troponin I Assay, Roche) resulted in an undetectable cardiac troponin I level, thus confirming the diagnosis.

RESUMEN

The optimal management of patients with cryptogenic stroke (CS) and patent foramen ovale (PFO) remains controversial. We conducted a meta-analysis to assess the effect of PFO closure for secondary prevention of stroke on patients with CS. We searched the literature for randomized control trials assessing the recurrence of stroke after PFO closure compared with medical therapy (antiplatelet and/or anticoagulation). Five randomized control trials with a total of 3,440 patients were included. The mean age was 45.2 ± 9.7 years and follow-up duration ranged from 2.0 to 5.9 years. PFO closure significantly reduced the risk of stroke compared with the medical therapy (2.8% vs 5.8%; relative risk [RR] 0.48, confidence interval [CI] 0.27 to 0.87, p = 0.01, I2 = 56%). The number needed to treat for stroke prevention was 10.5. PFO closure was associated with an increased risk of atrial fibrillation compared with medical therapy (4.2% vs 0.7%; RR 4.55, CI 2.16 to 9.6, p = 0.0001, I2 = 25%). There was no significant difference in all-cause mortality (RR 1.33, CI 0.56 to 3.16, p = 0.52, I2 = 0%), as well as no difference in bleeding risk between the 2 groups (RR 0.94, CI 0.49 to 1.83, p = 0.86, I2 = 29%). In conclusion, our meta-analysis demonstrates that PFO closure is associated with significantly lower risk of recurrent stroke in patients with PFO and CS compared with medical therapy. However, atrial fibrillation was more common among closure patients.

RESUMEN

BACKGROUND: The role of catheter ablation (CA) is increasingly recognized as a reasonable therapeutic option in patients with atrial fibrillation (AF) and heart failure (HF). HYPOTHESIS: We aimed to compare CA to medical therapy in AF patients with HF with reduced ejection fraction (HFrEF). METHODS: We searched the literature for randomized clinical trials comparing CA to medical therapy in this population. RESULTS: Six trials with a total of 775 patients were included. AF was persistent in 95% of patients with a mean duration of 18.5 ± 23 months prior enrollment. The mean age was 62.2 ± 7.8 years, mostly males (83%) with mean left ventricular ejection fraction (LVEF) of 31.2 ± 6.7%. Compared to medical therapy, CA has significantly improved LVEF by 5.9% (Mean difference [MD] 5.93, confidence interval [CI] 3.59-8.27, P < 0.00001, I2 = 87%), quality of life, (MD -9.01, CI -15.56, -2.45, P = 0.007, I2 = 47%), and functional capacity (MD 25.82, CI 5.46-46.18, P = 0.01, I2 = 90%). CA has less HF hospital readmissions (odds ratio [OR] 0.5, CI 0.32-0.78, P = 0.002, I2 = 0%) and death from any cause (OR 0.46, CI 0.29-0.73, P = 0.0009, I2 = 0%). Freedom from AF during follow-up was higher in patients who had CA (OR 24.2, CI 6.94-84.41, P < 0.00001, I2 = 81%. CONCLUSION: CA was superior to medical therapy in patients with AF and HFrEF in terms of symptoms, hemodynamic response, and clinical outcomes by reducing AF burden. However, these findings are applicable to the very specific patients enrolled in these trials.
