Effects of Two Different ACE Inhibitors, Captopril and Delapril, in the Early Phases of Acute Anterior Myocardial Infarction
1999
Objective: This study was aimed at investigating the effects of captopril or delapril before and just after thrombolysis in acute anterior myocardial infarction (AMI). Patients and Methods: Study participants consisted of 89 patients, hospitalised within 4 hours of the onset of symptoms. Patients were randomly divided into two groups: the first group (45 patients, pretreatment group) received captopril 6.25mg or delapril 7.5mg orally about 15 minutes before intravenous administration of recombinant tissue plasminogen activator (rt-PA) 100mg; the second group (44 patients, late-treatment group) received captopril or delapril about 4 to 6 hours after thrombolytic treatment. Captopril/delapril…
Role of antiangiogenic VEGF-A165b in angiogenesis and systolic function after reperfused myocardial infarction
2021
Abstract Introduction and objectives Angiogenesis helps to reestablish microcirculation after myocardial infarction (MI). In this study, we aimed to further understand the role of the antiangiogenic isoform vascular endothelial growth factor (VEGF)-A165b after MI and to explore its potential as a coadjuvant therapy to coronary reperfusion. Methods Two mice MI models were formed: a) permanent coronary ligation (nonreperfused MI); b) transient 45-minute coronary occlusion followed by reperfusion (reperfused MI); in both models, animals underwent echocardiography before euthanasia at day 21 after MI induction. We determined serum and myocardial VEGF-A165b levels. In both experimental MI models…

Cocaine-induced coronary thrombosis and acute myocardial infarction
2004
A 26-year-old man was admitted to our hemodynamic laboratory because of an anterior AMI and post myocardial infarction angina. He is an active smoker (10 cigarettes/day) and consumes inhaled cocaine during weekends (the last consumption of cocaine was 1 week ago). No others risk factors were recorded. Initial electrocardiogram shows sinus rhythm and anterior QS complex (V1–V3) with anterolateral ST segment elevation (V1–V5, D1 and aVL). Creatine-kinase isoenzyme MB and Troponin I were elevated at arrival. Upon admission, the patient was normotensive but with signs of pulmonary congestion. Ventriculography showed anterolateral and apical hypokinesia with an ejection fraction of 21%. Coronari…

Secondary adherence to beta-blockers after ST-elevation myocardial infarction without ventricular dysfunction.
2020
Introduction and objectives: Adequate medication intake affects treatment effectiveness. The aim of this study was to establish the impact of prescription and secondary adherence to beta-blockers on medium-and long-term and long-term cardiovascular outcomes, after a first type 1 ST-elevation myocardial infarction (STEMI) episode without heart failure or left ventricular ejection fraction >= 40%. Methods: A retrospective observational study was conducted in a cohort of patients admitted from 2008 to 2013 to the University Clinical Hospital in Valencia. Competing risk analysis assessed the relationship between cardiovascular mortality or new vascular event with beta-blocker prescription and s…
Effect of ischemic postconditioning on microvascular obstruction in reperfused myocardial infarction. Results of a randomized multicenter study in pa…
2013
Purpose: Ischemic Postconditioning (PCON) appears as a potentially beneficial tool to complement primary angioplasty in ST-segment elevation myocardial infarction (STEMI). We evaluated the impact of PCON on Microvascular Obstruction (MVO) both in patients and in a highly controlled swine model. Methods: In a multicenter study, 101 patients with a first STEMI were randomized to undergo primary angioplasty followed by PCON or primary angioplasty alone (non-PCON). MVO (lack of contrast uptake in the core of the hyperenhanced infarcted area) was quantified in late enhancement cardiac magnetic resonance imaging. In an anterior STEMI swine model based on a 90-min angioplasty balloon coronary occl…
Small, dense low-density-lipoproteins and the metabolic syndrome.
2006
Small, dense low-density-lipoproteins (LDL) are associated with increased risk for cardiovascular diseases and diabetes mellitus and a reduction in LDL size has been reported in patients with coronary and non-coronary forms of atherosclerosis. LDL size has been accepted as an important predictor of cardiovascular events and progression of coronary artery disease as well as an emerging cardiovascular risk factor by the National Cholesterol Education Program Adult Treatment Panel III. Small, dense LDL, with elevated triglyceride levels and low HDL-cholesterol concentrations, constitute the 'atherogenic lipoprotein phenotype (ALP)', a form of atherogenic dyslipidemia that is a feature of type …
Chronic Kidney Disease, Diabetes, and Risk of Mortality After Acute Myocardial Infarction: Insight From the FAST-MI Program
2020
Diabetes is associated with a substantially increased risk of all-cause death, mainly driven by cardiovascular (CV) mortality. Furthermore, diabetes is associated with poorer outcomes after acute myocardial infarction (AMI) (1). Impaired glomerular filtration rate (GFR) is also associated with an increased risk of CV mortality (2). However, whether diabetes still confers a higher risk of mortality in patients with impaired GFR remains unknown. The aim of this study was to assess the long-term prognostic significance of both diabetes and renal impairment in two prospective nationwide cohorts of AMI patients: FAST-MI (French Registry of Acute ST-Elevation or non-ST-elevation Myocardial Infarc…
