Active clinical trials for "Infarction"

It is a prospective, multicenter, randomised controlled, open-label, blinded endpoint assessment trial, to compare the strategy of immediate complete revascularisation and staged complete revascularisation in ST-segment-elevation myocardial infarction patients with multivessel coronary disease.

This study was performed as a randomized controlled a study with a pre test-post test design, aimed to determine affect of reflexology masagge to the pain, anxiety and comfort level on the patients that are percutaneous coronary intervention.

The goal of the proposed study is to determine whether a liberal transfusion strategy (transfusion trigger at Hb < 10 gm/dl) in Veterans at high cardiac risk who undergo major open vascular and general surgery operations is associated with decreased risk of adverse postoperative outcomes compared to a restrictive transfusion strategy (transfusion trigger at Hb < 7 gm/dl).

Incidence of ST-segment Elevation Myocardial Infarction (STEMI) is rising and the existing emergency medical aid system for STEMI was not enough for timely perfusion treatment. No existing research with high-quality data focuses on the characteristic of STEMI incidence and regional network construction. Aiming of Guangdong GAMI(reGional network for Acute Myocardial Infarction) project is to establish effective collaborative regional network system for STEMI patients treatment.

The purpose of this study is to look at the link between emotional stress and heart disease in men and women. Taking part in this study involves one clinic visit, one week of at home monitoring, and follow up phone calls every 6 months for 3 years.

The aim of this prospective randomized controlled clinical trial will evaluate the sensitivity, precision and effectiveness of photoelectrochemical immunosensor for early diagosis of acute myocardial infarction.

Magnetocardiography (MCG) is a non-invasive and accurate method of detecting myocardial ischemia. However, the previous MCG is limited in clinical practice due to its high working conditions and limited sensitivity. The next-generation MCG based on optical pumped magnetometer (OPM) has the advantages of high sensitivity, high reliability, high usability and low cost, which makes it suitable for most medical scenarios. Thus, this prospective single-center study aimed to use OPM MCG to explore its diagnostic efficacy and predictive value for myocardial ischemia. Participants who will receive coronary angiography examinations will be enrolled in this study. Participants enrolled in the study will also have a 1, 3, 6, 12, 24, 36, and 48-month follow-up for analysis of adverse cardiac events.

This study is being done to determine if taking an electrocardiogram (ECG) by a portable device (SmartHeart) followed by a phone call will improve patient outcomes by early recognition of abnormalities and decrease emergency room visits and hospital readmissions compared to standard therapy alone.

Among the patients diagnosed as acute myocardial infarction by coronary angiography, 5%-25% of the patients did not find coronary artery obstructive lesions. These patients do not need PCI. The discovery and verification of clinical protocols for accurate identification of myocardial infarction in the absence of obstructive coronary artery disease（MINOCA）is a major issue that needs to be addressed.Novel biomarkers like grow stimulation expressed gene 2（ST2）can indicate the degree of coronary artery obstruction, copeptin is a biomarker of cardiac emergency state. No clinical studies have been conducted to evaluate whether the novel biomarkers combination regimen can diagnose or exclude MINOCA. Our research aims to establish and validate a model for the recognition of MINOCA based on novel biomarkers (ST2, copeptin) and to evaluate the prognostic value of novel biomarkers among patients with acute chest pain.

Cardiac troponins are highly sensitive and specific biomarkers of cardiac injury and are in a key role in the diagnosis of acute myocardial infarction (MI). Minor troponin elevations are common after prolonged strenuous exercise without clinical symptoms of MI or myocardial injury. Importantly, currently used high-sensitivity troponin T (cTnT) test detects also smaller troponin fragments which may cause troponin elevation after exercise and lead to false diagnosis of MI. In the present study protocol, we compare the characteristics troponin release after marathon race and Type 1 MI with the improved version of our novel troponin fragmentation test (SuperTropo test) and the commercial cTnT test. A total of 65 recreational runners participating in the 2023 Paavo Nurmi Marathon in Turku are recruited. All participants give a blood sample during the post-race visit (within 30 min after finishing the marathon). A control group of 90 patients with acute Type 1 MI are recruited among patients admitted to Heart Centre of Turku University Hospital. Commercial cTnT and long troponin component of cTnT analyzed witha novel immunoassay are dtermined in all subjects to assess cTnT fragmentation. TYhe main aims of the study are: To assess how often cTnT is elevated after marathon running and which factors affect the cTnT rise? Is the fragmentation of troponin more common after marathon race compared with Type 1 MI and can the novel Supertropo test separate execise-induced troponin rise from those caused by MI ?
