Additional diagnostic value of systolic dysfunction induced by dipyridamole stress cardiac magnetic resonance used in detecting coronary artery disea…
2009
Dipyridamole stress perfusion cardiovascular magnetic resonance (CMR) is used to detect coronary artery disease (CAD). However, few data are available on the diagnostic value of the systolic dysfunction induced by dipyridamole. This study investigated whether the induction of systolic dysfunction supplements the diagnostic information provided by perfusion imaging in the detection of CAD.Overall, 166 patients underwent dipyridamole CMR and quantitative coronary angiography, with CAD being defined as a stenosisor =70%. Systolic dysfunction at rest, systolic dysfunction with dipyridamole, induced systolic dysfunction, and stress first-pass perfussion deficit (PD) and delayed enhancement were …
Tricuspid Regurgitation and Mortality Risk Across Left Ventricular Systolic Function in Acute Heart Failure.
2015
BACKGROUND Tricuspid regurgitation (TR) is a common echocardiographic finding that has been related to adverse outcome under various clinical scenarios. Nevertheless, evidence supporting its prognostic value in heart failure (HF) is scarce, and, in most cases, contradictory. We evaluated the association of TR grade with 1-year all-cause mortality in acute HF (AHF). METHODS AND RESULTS: We included 1,842 consecutive patients admitted for AHF. Mean age was 72.8±11.3 years, 51% were female and 45.5% had LVEF <50%. The severity of TR was graded in non-TR, mild (1), moderate (2), moderate-severe (3) and severe (4). At 1-year follow-up, 370 patients (20.1%) had died. In patients with LVEF ≥50%, a…
Diagnosis of silent coronary ischemia with selective coronary revascularization might improve 2-year survival of patients with critical limb-threaten…
2021
Abstract Background Patients with critical limb-threatening ischemia (CLTI) have had poor long-term survival after lower extremity revascularization owing to coexistent coronary artery disease. A new cardiac diagnostic test, coronary computed tomography-derived fractional flow reserve (FFRCT), can identify patients with ischemia-producing coronary stenosis who might benefit from coronary revascularization. We sought to determine whether the diagnosis of silent coronary ischemia before limb salvage surgery with selective postoperative coronary revascularization can reduce the incidence of adverse cardiac events and improve the survival of patients with CLTI compared with standard care. Metho…
Blood DNA Methylation and Incident Coronary Heart Disease
2021
IMPORTANCE American Indian communities experience a high burden of coronary heart disease (CHD). Strategies are needed to identify individuals at risk and implement preventive interventions. OBJECTIVE To investigate the association of blood DNA methylation (DNAm) with incident CHD using a large number of methylation sites (cytosine-phosphate-guanine [CpG]) in a single model. DESIGN, SETTING, AND PARTICIPANTS This prospective study, including a discovery cohort (the Strong Heart Study [SHS]) and 4 additional cohorts (the Women's Health Initiative [WHI], the Framingham Heart Study [FHS], the Atherosclerosis Risk in Communities Study ([ARIC]-Black, and ARIC-White), evaluated 12 American Indian…
Impact of perioperative transfusions and sepsis on long-term oncologic outcomes after curative colon cancer resection. A retrospective analysis of a …
2020
Objective: Intra-abdominal septic complications (IASC) affect short-term outcomes after surgery for colon cancer. Blood transfusions have been associated with worse short-term results.The role of IASC and blood transfusions on long-term oncologic results is still debated. This study aims to assess the impact of these two variables on survival after curative colon cancer resection. Patients and methods: Retrospective analysis of a prospectively maintained database of patients who underwent curative surgery for colon cancer at a university hospital, between 1993 and 2010. Cox regression was used to identify the role of IASC and transfusions (alone and combined) on local recurrence (LR), disea…
Low lymphocyte count in acute phase of ST-segment elevation myocardial infarction predicts long-term recurrent myocardial infarction
2010
Objective We sought to determine the relationship between the lowest lymphocyte count (lymphocyte(min))obtained within the first 96 h of symptoms onset and the risk of postdischarge recurrent spontaneous myocardial infarction (re-MI) in patients admitted with ST-segment elevation MI (STEMI). Methods We analyzed 549 consecutive patients admitted with STEMI from a single academic hospital. Lymphocyte counts were determined at admission and routinely during the first 96 h. Lymphocyte(min) was selected as the main exposure. Patients with inflammatory or infectious diseases, in-hospital death, or reinfarction were excluded from the analysis (final sample= 426 patients). Lymphocyte(min) was divid…
Length of stay and risk of very early readmission in acute heart failure
2016
In patients admitted for acute heart failure (AHF), optimal length of stay (LOS) remains controversial. Longer hospitalizations are associated with worse prognosis, but little is known about short hospitalizations. The aim of this work was to evaluate the relationship between LOS and the risk of short-term readmission in patients discharged after a hospitalization for AHF.We included 2110 consecutive patients. The independent associations between LOS and unplanned 10, 15 and 30-day readmissions were evaluated by Cox regression analysis adjusted for competing events. LOS was categorized as LOS1: ≤4days, LOS2: 5-7days, LOS3: 8-10days, and LOS4:10days.The mean age was 73±11years and 52.6% exhi…
Prognostic Value of White Blood Cell Count in Acute Myocardial Infarction: Long-Term Mortality
2005
Although traditionally an elevated white blood cell count (WBC), an indicator of systemic inflammation, has been accepted as part of the healing response following acute myocardial infarction (AMI), it has frequently been shown to be a predictor of adverse cardiovascular events. The present study was designed to assess the association between WBC and long-term mortality in AMI patients either with ST-segment elevation (STEMI) or without ST-segment elevation (non-STEMI). Patients and method. The study included 1118 consecutive patients who were admitted with the diagnosis of AMI: 569 non-STEMI and 549 STEMI. The WBC was measured in the 24 hours following admission. Patients were divided into…
Usefulness of the neutrophil to lymphocyte ratio in predicting long-term mortality in ST segment elevation myocardial infarction.
2007
Neutrophil to lymphocyte ratio (N/L) has been associated with poor outcomes in patients who underwent cardiac angiography. Nevertheless, its role for risk stratification in acute coronary syndromes, specifically in patients with ST-segment elevation myocardial infarction (STEMI), has not been elucidated. We sought to determine the association of N/L maximum value (N/L max) with mortality in the setting of STEMI and to compare its predictive ability with total white blood cell maximum count (WBC max). We analyzed 515 consecutive patients admitted with STEMI to a single university center. White blood cells (WBC) and differential count were measured at admission and daily for the first 96 hour…
Complete versus incomplete revascularization in patients with multivessel disease undergoing percutaneous coronary intervention with drug-eluting ste…
2008
Objectives: To investigate the long-term prognostic implications of complete versus incomplete revascularization in multivessel coronary artery disease (MVD) patients undergoing percutaneous coronary intervention (PCI) with drug-eluting stent (DES). Background: Coronary artery bypass grafting (CABG) in patients with MVD provides better outcomes when complete revascularization is achieved. There is a paucity of data on the outcomes of complete versus incomplete revascularization of MVD patients undergoing PCI, and currently there is no data available with DES. Methods: Patients with MVD undergoing PCI with DES (sirolimus- or paclitaxel-eluting stent) were included. Comparisons of long-term o…
