This study explored the impact of donor left ventricular ejection fraction (EF) and left ventricular wall thickness (LVWT) on mortality among heart transplant (HTx) recipients.
Utilizing data from ...the United Network for Organ Sharing (UNOS) registry, adult HTx recipients between 2006-2022 were analyzed. Patients were categorized into four groups based on donor EF(>50 % or ≤50 %) and LVWT(<1.4 cm or ≥1.4 cm).
21,012 patients were included. There were significant differences in baseline characteristics among the groups. Unadjusted mortality was 6.3 %, 6.0 %, 6.0 %, and 2.4 %(p=0.86) at 30-days; 16.2 %, 13.5 %, 16.8 %, and 7.3 %(p=0.08) at 1-year; and 32.2 %, 29.2 %, 35.4 %, and 29.0 %(p=0.18) at 5-years, respectively. In addition, adjusted mortality did not differ across the groups.
There were no significant differences in recipient mortality in groups based on donor EF and LVWT. Expanding the donor selection criteria would allow for increase in the donor pool and assist in decreasing the mortality, while on the waitlist for HTx.
Despite advances in the management of ST-elevation myocardial infarction (STEMI), when associated with heart failure (HF) its prognosis remains ominous. This study assessed the differences in ...admission and mortality of HF complicating STEMI at admission (HFad) in a middle-income country. Data from the National Registry of STEMI of Argentina (ARGEN-IAM-ST) from January 1, 2016, to September 30, 2020, were analyzed. HFad was defined by the identification of Killip/Kimball ≥2 at admission. About 3174 patients were analyzed (22.3% had HFad). Patients with HFad were older, more often women, hypertensive, and diabetic. Received less reperfusion (87.6% vs 92.6%, P < 0.001) and had increased in-hospital mortality (28.4% vs 3.0%, P < 0.001). In multivariate analysis HFad was an independent predictor of death (OR: 4.88 95%CI: 3.33-7.18, P < 0.001) and reperfusion adjusted to HFad was associated with lower mortality (OR: 0.57 95%CI: 0.34-0.95, P = 0.03). HFad in STEMI is associated with a worse clinical profile, receives fewer reperfusion strategies, and carries a higher risk of in-hospital mortality while reperfusion reduces mortality.
Infection caused by SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) exhibits a strong infectivity but less virulence compared to severe acute respiratory syndrome (SARS) and the Middle ...East respiratory syndrome (MERS). In terms of cardiovascular morbidity, susceptible population include elderly and patients with certain cardiovascular conditions. This infection has been associated with cardiac injury, cardiovascular complications and higher mortality.
The main objective of the CARDIO COVID 19-20 Registry is to determine the presence of cardiovascular comorbidities and cardiovascular complications in COVID-19 infected patients that required in-hospital treatment in different Latin American institutions.
The CARDIO COVID 19-20 Registry is an observational, multicenter, ambispective, and hospital-based registry of patients with confirmed COVID-19 infection who required in-hospital treatment in Latin America. Enrollment of patients started on May 01, 2020 and was initially planned to last three months; based on the progression of pandemic in Latin America, enrollment was extended until December 2020, and could be extended once again based on the pandemic course in our continent at that moment.
The CARDIO COVID 19-20 Registry will characterize the in-hospital population diagnosed with COVID-19 in Latin America in order to identify risk factors for worsening of cardiovascular comorbidities or for the appearance of cardiovascular complications during hospitalization and during the 30-day follow up period.
Heart failure complicating acute myocardial infarction marks an ominous prognosis. Killip and Kimball's classification of heart failure remains a useful tool in these patients. Lung ultrasound can ...detect pulmonary congestion but its usefulness in this scenario is unknown.
To investigate the diagnostic accuracy of lung ultrasound to predict heart failure in patients with acute myocardial infarction.
Patients admitted with acute myocardial infarction and without heart failure were evaluated with a lung ultrasound. The presence of B-lines was recorded and counted. The presence of new heart failure (Killip Class B, C, or D) during hospitalization was evaluated by a cardiologist blinded to the results of lung ultrasound. A ROC curve analysis was done to evaluate the diagnostic accuracy of B-lines to predict heart failure.
200 patients were included. Three patients were diagnosed with cardiogenic shock, 5 with acute pulmonary edema, and 17 with mild heart failure. Patients who develop heart failure had a median of 14 B-lines, however, patients who remained in Killip class A had a median of 2 (p = 0,0001). The area under the ROC curve of the sum of B-lines to predict any form of heart failure was 0,91 (CI95% 86–97). The best cut-off value was 5 B-lines, with a sensitivity of 88% (IC95% 68,8–97,5) and specificity of 81% (IC95% 73,9–86,2).
Lung ultrasound done at admission can help to predict heart failure In patients with acute myocardial infarction.
The shock index (IS) is the quotient between the heart rate (HR) and the systolic blood pressure (SBP) (IS: HR / SBT), and the age-adjusted shock index (ISA) multiplying the IS by age. We evaluated ...its predictive value for the combined in-hospital event (EC), death and / or cardiogenic shock (CS) and for individual events in the patients included in the Argentine registry of ST-segment elevation infarction (ARGEN-ST-AMI); 248 with CS on admission were excluded. ROC curves were made for both indices using the best cut-off point to dichotomize the population. The analysis included 2928 subjects. Age (median) 60 years (IQR 25-75% 53-68), men 80%, EC: 6.4%; 30.5% had IS = 0.67, and they had a higher incidence of EC: 11% vs. 4% (p < 0.001), cardiogenic shock (8% vs. 2.6%, p <0.0001) and death (7.3% vs. 3%), p <0.0001) than patients with IS < 0.67. A 28% had ISA = 41.5. These presented plus EC: 14% vs. 3%, p < 0.001, SC: 10% vs. 2%, (p < 0.001) and death: 9.5% vs. 2.3%, (p < 0.001) compared with patients with values < 41.5. The area under the ROC curve of the ISA for EC was significantly better than that of the IS (0.72 vs. 0.62, p < 0.001). In the multivariate analysis models performed, the IS had an OR: 2.56 (95% CI 1.56-4.02; p < 0.001) and the ISA: 3.43 (95% CI 2.08-5.65; p < 0.001) for EC. The IS and ISA predict death and / or the development of in-hospital cardiogenic shock in an unselected population of ST elevation infarcts.
To develop a clinical score to determine preclinical predictors of systolic dysfunction in an outpatient elderly population without a diagnosis of heart failure (HF). PULSE-HF is a cross-sectional ...study in elderly at-risk (coronary artery disease, diabetes or hypertension) outpatients without a diagnosis of heart failure (HF). The objective in this population was to develop a clinical score to determine preclinical predictors of systolic dysfunction. Clinical and geriatric variables were analyzed; independent predictive factors in the logistic regression analysis were included for the score calculation. Of the 722 subjects enrolled, 47 (6.5%) had a left ventricular ejection fraction (LVEF) < 50%, and 15 (2.1%) a LVEF < 40%. Mean age was 76.5 years (5.18) and 445 (61.6%) were female. Multiple logistic regression analysis identified abnormal Q waves (odds ratio OR: 4.36; P = 0.003), cardiomegaly (OR: 3.32; P < 0.001), right bundle branch block (OR: 2.84; P = 0.011), cognitive dysfunction (OR: 2.14; P = 0.027) and NT-proBNP (OR 5.43; P < 0.001) as independent predictors of LVEF < 50%. Two prediction scores were built, without and with NT-proBNP inclusion; the area under ROC curves were 0.70 and 0.76, respectively. As the score increased, the sensitivity decreases but increases specificity, and accuracy (97.17% and 91.64% respectively in ≥6 points). NT-proBNP was associated with an increment in the performance (accuracy of 93.18% for score ≥10). We conclude that a simple score using clinical information might be useful to predicting asymptomatic systolic dysfunction in the elderly.
The progression of chronic heart failure (CHF) is related to ongoing myocyte loss, which can be detected by cardiac troponin T (cTnT). We examined the prevalence and prognostic value of increased ...cTnT concentrations in serial blood specimens from patients with severe CHF.
Clinical, echocardiographic, and 6-minute walk test data were collected prospectively at baseline and at 1 year in 115 outpatients (mean age, 61+/-11 years; 75% men; 62% coronary heart disease) with CHF and a left ventricular ejection fraction <40%. Blood samples were collected at baseline and at 3, 6, and 12 months of follow-up. cTnT concentrations > or =0.02 ng/mL were considered abnormal, and a Tn index (highest cTnT measurement/0.02 ng/mL) was calculated. In 62 patients (54%), cTnT was consistently <0.02 ng/mL (group 1); 28 (24%) had a single abnormal cTnT result (group 2); and 25 (22%) had > or =2 abnormal cTnT results (group 3). At 18 months, CHF hospitalization-free survival was 63%, 46%, and 17%, respectively (P=0.0001). In a Cox proportional-hazards model, hospitalization for worsening CHF in the previous year (HR=2.1; 95% CI, 1.1 to 4.1), functional class III-IV (HR=2.3; 95% CI, 1.1 to 4.6), and number of abnormal cTnT samples (HR=1.6; 95% CI, 1.1 to 2.4) were independently associated with prognosis. A cTnT rise of 0.020 ng/mL in any sample was associated with an excess of 9% (95% CI, 1% to 18%) in the incidence of combined end point.
Abnormal cTnT concentrations were detected in >50% of outpatients with advanced CHF. This ongoing myocardial necrosis was a strong predictor of worsening CHF, suggesting a role of cTnT-based monitoring to identify high-risk patients.
Background: Socioeconomic factors contribute to a more severe impact of COVID-19 in Latin American and Caribbean (LA&C) countries than in developed countries. Patients with a severe or critical ...illness can develop respiratory and cardiovascular complications.
Objective: To describe a LA&C population with COVID-19 to provide information related to this disease, in-hospital cardiovascular complications, and in-hospital mortality.
Methods: The CARDIO COVID-19–20 Registry is an observational, multicenter, prospective, and hospital-based registry of patients with confirmed COVID-19 infection that required in-hospital treatment in LA&C. Enrollment of patients started on May 01, 2020, and ended on June 30, 2021.
Results: The CARDIO COVID-19–20 Registry included 3260 patients from 44 institutions of 14 LA&C countries. 63.2% patients were male and median age was 61.0 years old. Most common comorbidities were overweight/obesity (49.7%), hypertension (49.0%), and diabetes mellitus (26.7%). Most frequent cardiovascular complications during hospitalization or reported at discharge were cardiac arrhythmia (9.1%), decompensated heart failure (8.5%), and pulmonary embolism (3.9%). The number of patients admitted to the Intensive Care Unit (ICU) was 1745 (53.5%), and median length of their stay at the ICU was 10.0 days. Support required in ICU included invasive mechanical ventilation (34.2%), vasopressors (27.6%), inotropics (10.3%), and vasodilators (3.7%). Rehospitalization after 30-day post discharge was 7.3%. In-hospital mortality and 30-day post discharge were 25.5% and 2.6%, respectively.
Conclusions: According to our findings, more than half of the LA&C population with COVID-19 assessed required management in ICU, with higher requirement of invasive mechanical ventilation and vasoactive support, resulting in a high in-hospital mortality and a considerable high 30-day post discharge rehospitalization and mortality.
The epidemiology of pulmonary hypertension (PH), especially pulmonary arterial hypertension (PAH), has not been evaluated in our country, therefore there is no reference parameter to establishing the ...representativeness of this information in the national order. This registry represents the first collaborative effort to provide a knowledge base of this disease, including 5 scientific societies that represent different specialties (pediatrics, rheumatology, pulmonology and cardiology) with data from 23 Argentine provinces. These efforts involved five societies of various adult (cardiology, rheumatology, and pulmonology) and pediatric (cardiology) specialties. Subjects were grouped (1-5) in accord with the 2013 Nice classification. A total of 627 patients (mean age, 50.8 ± 18 years; women, 69.2%) were recruited. Incident cases accounted for 53%. Functional class III-IV accounted for 69% at time of diagnosis and 33.4% at time of inclusion. Distributions in groups 1-5 were 63.6%, 15.9%, 8.3%, 9.7%, and 2.4%, respectively. Treatment consisted of diuretics (51.2%), mineralocorticoid receptor antagonists (44.7%), digoxin (16.6%), anticoagulants (39.2%), renin-angiotensin antagonists (15.5%), beta blockers (15.6%), and calcium channel blockers (8%). Rates of specific therapies usage in PAH vs. non-PAH group were 80.5% vs. 40.8% (phosphodiesterase-5 inhibitors: 71% vs. 38.6%; endothelin receptor antagonists: 54.4% vs. 14.5%; prostanoids: 14.3 vs. 3.1%; all p < 0.001). Three-year survival in PAH and non-PAH differed significantly (82.8% vs. 73.3%; p = 0.001). In the Argentine RECOPILAR registry, the clinic-epidemiologic profile was that of advanced-stage disease. Diagnostic workups and therapeutics interventions, including use of specific therapy for PAH, were consistent with current recommendations. Despite delays in diagnosis, survival was aligned with other contemporary registries.
