Active clinical trials for "Infarction"

To evaluate the relationships of compliance in taking aspirin or aspirin placebo with the risk of major cardiovascular endpoints, using data collected in the Physicians' Health Study.

To evaluate factors associated with cardiovascular morbidity and mortality in a cohort of 795 men and women aged 75 years or older at the time of a comprehensive examination conducted between 1984 and 1987.

To test the hypotheses that the risk of myocardial infarction and/or stroke is associated with elevated plasma levels of homocysteine, and low plasma levels of folate, vitamins B12 and B6.

To analyze existing data from the Physicians Health Study (PHS), a randomized primary prevention trial of low-dose aspirin and beta carotene conducted among 22,071 U.S. male physicians, to address questions concerning aspirin and cardiovascular (CV) disease that could not adequately be addressed during the randomized aspirin period.

High-sensitive cardiac troponin T (hs-cTnT) is a cornerstone for diagnosing acute myocardial infarction (AMI). However, it is often challenging to diagnose AMI in patients with elevated hs-cTnT before a rise or fall of hs-cTnT can be observed. The elevations of hs-cTnT are caused not only by AMI, but also by other cardiac or even non-cardiac diseases. Thresholds above the 99th percentile have been proposed to improve the specificity and to accelerate the rule in of myocardial infarction. This study aimed to find a more accurate cut-off value to rule in AMI in patients with elevated hs-cTnT.

Obstructive Sleep Apnea (OSA) is a well-known disorder of upper airways collapse during sleep time leading to oxygen desaturation and sleep fragmentation. Despite being increasingly recognized as cardiovascular risk, the effect of OSA on clinical outcomes after Acute Coronary Syndrome (ACS) is not fully defined. Also, OSA syndrome is highly prevalent in ACS and may be related to the deterioration of cardiac function resulting in worsening of the severity of sleep apnea or the intermittent hypoxia could be cardio-protective via the ischemic preconditioning event. Serial sleep studies have shown the progressive reduction of the Apnea / Hypopnea Index (AHI) from the admission in Coronary Care Unit (CCU) to 6 weeks, 12 weeks and 6-month follow up, making necessary to re-assess the severity of OSA after discharge. Therefore, further research in this field is necessary to screen and predict those ACS patients who may experience a change in their AHI index over time.

This study examined the risk factors and the influence of the type of anesthetic used during transurethral resection of the prostate (TURP) on subsequent incidence of myocardial infarction (MI).

Cardiovascular disease, and in particular ischemic heart disease, is the main cause of morbidity and mortality worldwide today (1). Myocardial infarction (MI) presents the most serious clinical entity through its short-term life threatening involvement. The many advances in the management of IDM during the acute phase, namely the increasingly frequent and effective use of reperfusion means (angioplasty and thrombolysis) as well as pharmacological progress, in particular, the management of anti-thrombotic treatment has enabled a significant reduction in intra-hospital mortality, in the medium and long term (2). In fact, the mortality rate dropped from 25-30% before the creation of the cardiac intensive care units (ICUS) around the 1960s, to around 16% in the 1980s and reaching 4 to 6% today. In the latest data from the French FAST MI 2015 register (French Registry of Acute ST-Elevation or Non-ST-elevation Myocardial Infarction) mortality was 2.8% in hospital (3) and 5.3% at 6 months (4). Nevertheless, mortality rates diverge from one register to another and are generally higher compared to randomized controlled clinical trials. In our country, due to the aging of the Tunisian population (currently the oldest population in Africa), as well as the rise in the prevalence of cardiovascular risk factors (5), the incidence of IDM is clearly increasing. However, our local specificities concerning the management of this pathology and the intra-hospital mortality which results from it, remain little described despite the importance of these data in the development of personalized algorithms and the improvement of the quality of this support. the management of CAD ST + in the public sector poses more and more efficiency problems and moves away from international recommendations in our country, an assessment of our national situation is necessary. The objectives of the study are, primary, the incidence of new cases that consult the emergency room for CAD ST + and the treatment delivered to the emergency room, in particular the nature of the treatment for obstruction (primary angioplasty or thrombolysis). Secondary, the evaluation of hospital complications and the future of patients on D30 and after one year from the inclusion's day.

The HIV/HEART Aging study (HIVH) is an ongoing, prospective, multicentre trial that was conducted to assess the incidence, the prevalence and the clinical course of cardiovascular diseases (CVD) in HIV-infected patients. The study population includes outpatients from specialized HIV-care units of the German Ruhr region, who were at least 18 years of age, were known to have a HIV-infection and exhibited a stable disease status within 4 weeks before inclusion into the trial. From March 2004 (Pilot phase) to October 2019 (12,5 year Follow-up) 1806 HIV+ patients were recruited in a consecutive manner. The standardised examinations included a targeted assessment of medical history and physical examination. Blood was drawn for comprehensive laboratory tests including HIV specific parameters (CD4 cell count, HIV-1 RNA levels) and cardiovascular items (lipid concentrations, BNP values and renal parameters). Furthermore, non-invasive tests were performed during the initial visit, including additional heart rate and blood pressure measurements, electrocardiogram (ECGs) and transthoracic echocardiography (TTE). Examinations were completed in accordance with previously defined standard operating procedures. CVD were defined as coronary, cerebrovascular, peripheral arterial disease, heart failure or cardiac vitium.

The purpose of this study is to explore the serum levels of pro- and anti-inflammatory biomarkers and angiogenic growth factors and SNP polymorphisms of the promoter regions of their genes as well as to determine their role in the development of adverse cardiac remodeling in patients with acute ST-segment elevation myocardial infarction.
