Smoking ban in public places and myocardial infarction hospitalizations in high cardiovascular risk European country – insights from the Polish natio…

2019

Introduction Previous studies demonstrated a possible positive effect of a smoking ban in public places on cardiovascular outcomes. However, little is known about the influence of such regulations in Poland, a country with a high cardiovascular risk. Objectives We aimed to evaluate the association of hospitalization rates for acute myocardial infarction (AMI) in Poland before and after the introduction of the smoking ban in public places in November 2010. Patients and methods The Nationwide Acute Myocardial Infarction Database (AMI‑PL) was searched for the cases of AMI that occurred between 2009 and 2014. The analysis considered sex, age (20-64 years vs 65 years or older), and the place of …

[Pharmacological treatment of depression after acute myocardial infarction].

2005

Depressed mood and other depressive symptoms frequently appear after acute myocardial infarction and it is known how these patients have an increased risk for morbidity and mortality compared to patients without depression. Many risk factors promote the development of clinical depression in patients with recent myocardial infarction. Although a large number of studies underline the negative prognostic impact of depression on the infarcted patient, only rarely depressed patients are appropriately diagnosed and treated. Furthermore it should be borne in mind that the use of psychotropics in medically ill patients requires attention. These compounds, in fact, may interact with the disease caus…

Association between dietary fibre intake and fruit, vegetable or whole-grain consumption and the risk of CVD: results from the PREvención con DIeta M…

2016

Prospective studies assessing the association between fibre intake or fibre-rich food consumption and the risk of CVD have often been limited by baseline assessment of diet. Thus far, no study has used yearly repeated measurements of dietary changes during follow-up. Moreover, previous studies included healthy and selected participants who did not represent subjects at high cardiovascular risk. We used yearly repeated measurements of diet to investigate the association between fibre intake and CVD in a Mediterranean cohort of elderly adults at high cardiovascular risk. We followed-up 7216 men (55-80 years) and women (60-80 years) initially free of CVD for up to 7 years in the PREvención con…

Automated detection and localization system of myocardial infarction in single-beat ECG using Dual-Q TQWT and wavelet packet tensor decomposition.

2019

Abstract Background and objective It is challenging to conduct real-time identification of myocardial infarction (MI) due to artifact corruption and high dimensionality of multi-lead electrocardiogram (ECG). In the present study, we proposed an automated single-beat MI detection and localization system using dual-Q tunable Q-factor wavelet transformation (Dual-Q TQWT) denoising algorithm. Methods After denoising and segmentation of ECG, a fourth-order wavelet tensor (leads × subbands × samples × beats) was constructed based on the discrete wavelet packet transform (DWPT), to represent the features considering the information of inter-beat, intra-beat, inter-frequency, and inter-lead. To red…

Number of drugs used in secondary cardiovascular prevention and late survival in the population of Valencia Community, Spain.

2019

Abstract Background Drug treatment for secondary prevention of cardiovascular disease is recommended by guidelines, but it is not always followed in real life. This study wanted to assess the size of this gap and its impact on mortality in subjects after a cardiovascular event (MACE). Methods Patients with any of MACE in the period from January 1st 2011 to December 31st 2013, and more than one year of follow-up were selected from population of the Valencian Community. Drugs for secondary prevention were antiplatelets, renin-angiotensin system blockers and statins. Assessment of treatment was performed one year after the initial event. Mortality risk was assessed using Cox by the number of d…

Intravenous BQ-123 and phosphoramidon reduce ventricular ectopic beats and myocardial infarct size in dogs submitted to coronary occlusion and reperf…

2001

Abstract The aim of this work was to investigate the influence of endothelin on myocardial ischemia and reperfusion in anaesthetized dogs. Animals were submitted to left thoracotomy and 120 min of left anterior descending coronary occlusion, followed by 180 min of reperfusion. Arterial blood pressure and electrocardiogram (ECG) were recorded in order to analyze heart rate (HR)–pressure product and production of ectopic beats. Infarcted areas were identified by a macroscopic staining method and infarct size was expressed as percentage of risk zone. To inhibit the effects of endothelin in a group of animals, we administered intravenously an endothelin synthesis inhibitor (phosphoramidon) and …

Magnetic Resonance MicroImaging of a Swine Infarcted Heart: Performing Cardiac Virtual Histologies

2015

The aim of this study is to develop a computer-aided intuitive software tool based on MATLAB to reproduce the functions of a virtual histology over Magnetic Resonance (MR) microimages of small samples of swine's infarcted hearts. The basic characterization consists of selecting regions of interest (ROIs) of that MR microimage and extracting the most important information of these regions. The software tool will implement intuitive and sophisticated tools that allow the user to define ROIs on the different types of images provided by the MR scanner. The final purpose of this tool will be to analyze the acquired data in order to characterize some aspects of the later possible events after a m…

Silent and symptomatic atrial fibrillation,during the acute phase of myocardial infarction : determinants and role of arginine methylated and oxidati…

2015

Atrial fibrillation (AF) is a frequent complication of acute myocardial infarction (AMI) with a poorer prognosis. Silent atrial fibrillation has been suggested to be frequent after AMI. However, most part of the studies has targeted only paroxysmal or persistent AF. Thus, Reduced Nitric Oxide availability and endothelial dysfunction has been recently recognized as a possible contributor to altered prognosis in AF. Asymmetric dimethylarginine (ADMA) can inhibit nitric oxide synthase and leads to endothelial dysfunction, inflammation and oxidative stress in multiple cardiovascular diseases. However, any study has addressed the relationship between ADMA levels and the occurrence of AF in AMI.W…

Objective: Growth differentiation factor-8 (GDF8), also known as myostatin, is a member of the transforming growth factor-β superfamily that inhibits skeletal muscle growth. We aimed to investigate the association between GDF8 and peak troponin I levels after acute myocardial infarction (AMI). Methods: All consecutive patients admitted from June 2016 to February 2018 for type 1 AMI in the Coronary Care Unit of University Hospital of Dijon Bourgogne (France) were included in our prospective study. Blood samples were harvested on admission, and serum levels of GDF8 were measured using a commercially available enzyme-linked immunosorbent assay kit. Results: Among the 296 patients with type 1 A…

Atherogenic Ratios in Patients with Recurrent Acute Coronary Syndrome and Receiving Statin Therapy: Clinical Usefullness as Cardiovascular Predictors

2015

Patients who have already suffered a vascular event require more and better control of cardiovascular risk factors. Different atherogenic indexes such as TC/HDLc, LDLc/HDLc, apoB/apoA-I, LDLc/apoB and non-HDLc/HDLc have been used to follow-up the patients because of their predictive capacity of the lipid profile. The aim of this study was to evaluate atherogenic ratios as a marker of the lipid residual risk in high-risk patients receiving statin therapy and to know the changes produced by previous lipid-lowering drugs treatment for a previous coronary event. The study including patients admitted to coronary care units of six Spanish tertiary hospitals for Acute Coronary Syndrome (ACS). A to…
