Filter by: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 retrospective cohort study is to identify triggers of heart failure (HF) development and drivers of HF progression as well as the underlying cardiac disease (phenotype) to identify patients at risk and predict the clinical course of the disease. Data of patients who were hospitalized during the years 2010-2023 with acute coronary syndrome (ACS) and/ or with acute heart failure (AHF) will be collected and analyzed. In a subgroup cohort efficacy and safety of digoxin in patients with acute heart failure triggered by tachyarrhythmia will be evaluated.
This pilot randomized controlled trial aims to evaluate the feasibility for safety examination of continued metformin therapy in patients with type 2 diabetes (T2D) following invasive coronary angiography. Metformin will be continued until coronary angiography.
Coronary heart disease, including acute coronary syndromes (ACS), is the leading cause of death in European countries. One of the basic elements of secondary and tertiary prevention of ACS is cardiac rehabilitation. The aims of the study are evaluation of the impact of cardiac rehabilitation on health state- especially on cardiovascular function parameters in patients after acute coronary syndrome and evaluation of the influence of the level of gene expression and polymorphisms of genes associated with ischemic heart disease on the course of cardiac rehabilitation in patients after ACS. The study will consist of a retrospective and prospective part. The retrospective part will include patients who have had acute coronary syndrome in the past and then - before being included in the study - have undergone cardiac rehabilitation. In the retrospective part, patients enrolled in the study will not undergo cardiac rehabilitation as a part of the study intervention. The prospective part will include patients who have had an acute coronary syndrome in the past and will undergo cardiac rehabilitation as the study intervention. After being included in the study, patients will undergo medical examination. Then subsequent procedures will be performed: anthropometric measurements; ECG; body composition analysis by bioimpedance; measurement of resting blood pressure, resting heart rate and oxygen saturation of hemoglobin; pulse wave analysis; transthoracic echocardiography of the heart; 24-hour blood pressure measurement by ambulatory blood pressure monitoring (ABPM); 24-hour ECG recording using the Holter method; electrocardiographic exercise test on a treadmill and / or a six-minute walk test or other exercise test adequate to the patient's state of health; assessment of the quality of the diet; assessment of lifestyle, acceptance of disease and quality of life; assessment of the psychological profile. Subsequently patients taking part in the prospective part of the study will perform a cardiac rehabilitation program. After the cardiac rehabilitation program measurement procedures listed above will be repeated. Before and after the cardiac rehabilitation program blood samples, urine samples and hair samples will be collected. Blood samples, urine samples and hair samples will also be collected from patients taking part in the retrospective part of the study.
The investigators will enroll the patients who underwent PCI and was based on real world clinical practice to collect the data regarding demographic, clinical, procedural information and clinical outcome using case report forms.
A total of 100 patients with non-ST-segment elevation acute coronary syndromes with or without diabetes mellitus will be included. All patients will undergo coronary angiography with identification of the infarct-related vessel and percutaneous revascularization with implantation of a stent/scaffold. After revascularization patients will undergo a combined positron emission tomography (PET)-coronary computed tomography (CT) protocol to quantify atherosclerotic burden (i.e. plaque volume) and activity (i.e. 18 fluorum-sodium-fluoride [18FNaF] uptake) in non-infarct related vessels, to assess calcium score (aim 1), and to quantify the acute results of PCI in the infarct-related vessel (aim 2). At 12-month follow-up, all patients will repeat longitudinal 18FNaF PET-coronary CT evaluation to characterize progression of atherosclerosis in the non-infarct related vessels (aim 1) and to quantify neointimal suppression at the site of the treated coronary segment in the infarct-related vessel (aim 2). Blood samples will be collected at baseline and 12 months for all patients. The aims of the study are: 1. To evaluate coronary artery disease progression in acute coronary syndromes patients with and without diabetes mellitus, and to investigate the predictive value of metabolic profiles, patterns of circulating miRNAs and inflammatory mediators on coronary artery disease progression; 2. To evaluate the progression of disease within the infarct-related vessel treated with the use of bioresorbable stent/bioresorbable polymer stents in diabetic and non-diabetic patients with acute coronary syndromes.
AMIPE is both a retrospective and prospective study which was designed in order to collect data of patients with acute coronary syndromes and myocardial injury and to improve the knowledge about these conditions.
The investigator aimed to evaluate the long-term (up to 10 years) follow-up of the patients who enrolled the IVUS-XPL study (Impact of IntraVascular UltraSound Guidance on the Outcomes of Xience Prime Stents in Long Lesions), which was shown the superiority of IVUS-guided stent implantation at 1 year in terms of major adverse cardiac events.
The objective of this research study is to test the accuracy of preexisting criteria versus expert interpretation for the diagnosis of acute coronary occlusion (major heart attack due to a completely blocked blood vessel). If our hypothesis proves to be true, this would provide a significant improvement in the care for patients who present to the hospital with possible symptoms of coronary ischemia (symptoms due to lack of blood flow to the heart). The primary analysis will be designed as a multi-center, retrospective case-control study.
Rationale: Acute coronary syndrome (ACS) is the leading cause of death worldwide. To improve cardiovascular care, research is needed. Current guidelines are mainly based on well controlled RCT's, though evaluation of the impact of such RCT's in the real world is missing. In order to evaluate the impact and to overcome certain limitations of RCT's, a more practical approach is required. In this sense the use of nonrandomized observational studies is an important tool for determining the effectiveness of a therapy in routine clinical practice. One way to gain insight in characteristics of patients presenting in daily clinical practice, is to simply register these characteristics in a prospective manner with adequate follow up. Objective: To create an ongoing registry for evaluation of clinical long-term impact of diagnostics, various treatments and devices used for ACS, for research and evaluation of quality of care and to evaluate and improve regional quality of care and cooperation between PCI and non-PCI centers.
