Post infarction heart failure

Red blood cell (RBC) transfusion therapy is often performed in patients with acute heart failure (AHF) and anemia; however, its impact on subsequent cardiovascular events is unclear. We examined whether RBC transfusion influences major adverse cardiovascular events (MACE) after discharge in patients with AHF and anemia.We classified patients with AHF and anemia (nadir hemoglobin level < 10 g/dL) according to whether they received RBC transfusion during hospitalization. The endpoint was MACE (composite of all-cause death, non-fatal acute coronary syndrome/stroke, or heart failure readmission) 180 days after discharge...

In patients with hypertension and pre-frailty or frailty, the influence of systolic (SBP) and diastolic blood pressure (DBP) time in target range (TTR) on clinical outcomes is unclear. Thus, we conducted a post hoc analysis of the Systolic Blood Pressure Intervention Trial (SPRINT). Classifying 4208 participants into frail and non-frail groups using a frailty index, the study calculated blood pressure time in target range (BP-TTR) for the first three months using the Rosendaal method. The primary endpoint included a composite of nonfatal myocardial infarction (MI), acute coronary syndromes, stroke, acute decompensated heart failure (ADHF), and cardiovascular death...

BACKGROUND: Downregulated expression of cold-inducible RNA binding protein (CIRP), a stress-response protein, has been demonstrated in the hearts of patients with heart failure (HF). However, whether CIRP plays a critical role in the pathogenesis of HF remains unknown. Zr17-2 is a recently identified CIRP agonist, which can enhance the expression of CIRP in hearts. Herein, we evaluated the effects of zr17-2 on the development of HF in a rat model of myocardial infarction (MI). METHODS: Male SD rats were pretreated with CIRP agonist zr17-2 or vehicle saline for 6 consecutive days, followed by MI induction...

Heart failure is the prevalent complication of acute myocardial infarction. We aim to identify a biomarker for heart failure post-acute myocardial infarction. This observational study includes 1062 and 1043 patients with acute myocardial infarction in the discovery and validation cohorts, respectively. The outcomes are in-hospital and long-term heart failure events. S100A8/A9 is screened out through proteomic analysis, and elevated circulating S100A8/A9 is independently associated with heart failure in discovery and validation cohorts...

PURPOSE: To assess whether transarterial embolization using adjunctive techniques according to angioarchitectural types is effective for treating renal arteriovenous malformations (rAVMs). MATERIALS AND METHODS: Overall, 18 patients with rAVM (type 1, n=7; type 2, n=2; type 3, n=9; mean age: 53.8) who underwent 25 procedures, in total, between 2011 and 2022 were reviewed. The clinical characteristics, endovascular techniques, AVM occlusion rate, adverse events (including the incidence of renal infarction), and clinical outcomes (including recurrence/aggravation of AVM) and symptoms were analyzed according to the angioarchitectual types...

OBJECTIVE: This study aimed to evaluate the SpO2 (transcutaneous oxygen saturation) -mortality link in elderly T2DM (diabetes mellitus type 2) patients with cerebral infarction and identify their optimal SpO2 range. METHODS: In this investigation, we employed a comprehensive approach. Initially, we screened the MIMIC-IV database, identifying elderly T2DM patients with cerebral infarction, utilizing specific ICD-9 and ICD-10 codes. We then harnessed the power of restricted cubic splines to craft a visual representation of the correlation between SpO2 and 1-year mortality...

BACKGROUND: There has been an evolution in the disease severity and complexity of patients presenting to the cardiac intensive care unit (CICU). There are limited data evaluating the role of palliative care in contemporary CICU practice. METHODS: PubMed Central, CINAHL, EMBASE, Medline, Cochrane Library, Scopus, and Web of Science databases were evaluated for studies on palliative care in adults (≥18 years) admitted with acute cardiovascular conditions - acute myocardial infarction, cardiogenic shock, cardiac arrest, advanced heart failure, post-cardiac surgery, spontaneous coronary artery dissection, Takotsubo cardiomyopathy, and pulmonary embolism - admitted to the CICU, coronary care unit or cardiovascular intensive care unit from 1/1/2000 to 8/8/2022...

BACKGROUND: Prostaglandin E2 acts through 4 G-protein-coupled receptors (EP1-EP4). We previously reported that activation of the EP3 receptor reduces cardiac contractility, and its expression increases after a myocardial infarction (MI), mediating the reduction in cardiac function. In contrast, cardiac overexpression of the EP4 receptor in MI substantially improves cardiac function. Moreover, we recently reported that mice overexpressing EP3 have heart failure under basal conditions and worsened cardiac function after MI...

Left ventricular assist device (LVAD) implantation is an effective alternative treatment to heart transplantation, especially for end-stage heart failure patients who are ineligible for or unable to await a heart transplant. This report describes a complex and innovative surgery where LVAD implantation was performed alongside multiple concomitant cardiac and aortic procedures. A 62-year-old male patient with complicated comorbidities developed acute myocardial infarction and subsequent refractory advanced heart failure...

BACKGROUND: Valsartan is commonly used for cardiac conditions. In 2018, the Food and Drug Administration recalled generic valsartan due to the detection of impurities. Our objective was to determine if heart failure patients receiving valsartan at the recall date had a greater likelihood of unfavorable outcomes than patients using comparable antihypertensives. METHODS: We conducted a cohort study of Optum's de-identified Clinformatics® Datamart (July 2017-January 2019)...

BACKGROUND: Cardiovascular disease (CVD) is the leading cause of mortality in kidney transplant (KT) patients. The perceived risk of contrast-induced nephropathy (CIN) may create a reluctance to perform coronary angiography in patients presenting with non-ST segment elevation myocardial infarction (NSTEMI). METHODS: National Inpatient Sample (NIS) Database was used to sample individuals presenting with NSTEMI. Patients were stratified into KT and Non-KT cohorts...

BACKGROUND: Myocardial infarction and non-obstructive coronary arteries (MINOCA) affects 1 in 9 patients with acute coronary syndrome and has no evidence-based therapy. NT-proBNP is an established biomarker associated with prognosis in heart failure and ischemic heart disease, although there is a paucity of data in patients with MINOCA. METHODS: Prospective study of the diagnostic and clinical utility of measuring NT-proBNP in patients with MINOCA without left ventricular dysfunction or heart failure...

BACKGROUND: Epidemiological investigations suggest that patients with heart failure have a higher incidence of cancer; however, the causal role of cardiac disease on cancer progression remains unclear. OBJECTIVES: This study aimed to investigate the impact and underlying mechanisms of myocardial infarction (MI)-induced heart failure on tumor cell growth. METHODS: We generated a syngeneic mouse model by implanting mammary tumor-derived 4T1 cells into BALB/c mice with MI resulting from ligation of the left anterior descending artery...

BACKGROUND: Although numerous studies have examined readmission with heart failure (HF) after acute myocardial infarction (AMI), limited data are available on HF readmission in cancer patients post-AMI. OBJECTIVES: This study aimed to assess the rates and factors associated with HF readmission in cancer patients presenting with ST-segment elevation myocardial infarction (STEMI). METHODS: A nationally linked cohort of STEMI patients between January 2005 and March 2019 were obtained from the UK Myocardial Infarction National Audit Project registry and the UK national Hospital Episode Statistics Admitted Patient Care registry...

OBJECTIVES: This study aimed to evaluate the efficacy and safety of finerenone, a selective, non-steroidal mineralocorticoid receptor antagonist, on cardiovascular and kidney outcomes by age and/or sex. DESIGN: FIDELITY post hoc analysis; median follow-up of 3 years. SETTING: FIDELITY: a prespecified analysis of the FIDELIO-DKD and FIGARO-DKD trials. PARTICIPANTS: Adults with type 2 diabetes and chronic kidney disease receiving optimised renin-angiotensin system inhibitors (N=13 026)...

PURPOSE: The aim of this investigation was to evaluate the impact of automated cardiac rehabilitation (CR) referral and nurse care coordination on patient and program outcomes. Specifically, the aim was to identify whether differences exist in physical and psychological function at CR Phase 2 enrollment and completion and CR Phase 2 participation and completion for hospitalized patients who receive in-person CR nurse visits versus phone consultation. Using a retrospective pre-/post-intervention descriptive design, a purposive sampling technique was used to select groups with matching clinical attributes...

AIM: We evaluated the incidence and relative risk of major post-acute cardiovascular consequences of SARS-CoV-2 infection in a large real-world population from a primary care database in a region at moderate cardiovascular risk followed up in the period 2020-2022. METHODS AND RESULTS: This is a retrospective cohort analysis using data from a cooperative of general practitioners in Italy. Individuals aged >18 affected by COVID-19 starting from January 2020 have been followed for three years...

BACKGROUND: Liver transplant (LT) patients have become older and sicker. The rate of post-LT major adverse cardiovascular events (MACE) has increased, and this in turn raises 30-d post-LT mortality. Noninvasive cardiac stress testing loses accuracy when applied to pre-LT cirrhotic patients. AIM: To assess the feasibility and accuracy of a machine learning model used to predict post-LT MACE in a regional cohort. METHODS: This retrospective cohort study involved 575 LT patients from a Southern Brazilian academic center...

The body surface potential mapping of the heart during the period of ventricular depolarization and the inotropic function of the ventricles were studied in rats under conditions of a translational model of post-infarction chronic heart failure developed by us. We revealed a statistically significant (p<0.001) correlation between the left-ventricular ejection fraction and the values of the maximum positive and negative extrema of the cardioelectric field on the body surface of rats with post-infarction chronic heart failure caused by anterior transmural myocardial infarction...

BACKGROUND: Myocardial infarction (MI) and heart failure are associated with an increased incidence of cancer. However, the mechanism is complex and unclear. Here, we aimed to test our hypothesis that cardiac small extracellular vesicles (sEVs), particularly cardiac mesenchymal stromal cell-derived sEVs (cMSC-sEVs), contribute to the link between post-MI left ventricular dysfunction (LVD) and cancer. METHODS: We purified and characterized sEVs from post-MI hearts and cultured cMSCs...
