Microvascular Angina Intervention With Compound Danshen Dripping Pill (MAIDS)
Coronary microvascular disease (MVD) refers to exertional angina or myocardial ischemia caused by abnormal structure and/or function of precoronary arterioles and arterioles under the action of various pathogenic factors. The symptoms of patients with coronary microvascular disease are mainly exertion-related chest pain episodes. The basic and clinical researches of the …
RNA as Prognostic Biomarkers in Patients With Acute Coronary Syndrome
Identify circulating protein-coding (mRNAs) or non-coding (ncRNAs) transcripts (ACS_signature) predictive of ventricular dysfunction in ACS patients undergoing PCI.
Cerebral Oxygenation and Burst Suppression
investigators want to observe a group of pediatric patients who are going to undergo open thoracic surgery at Queen Silvia's child and youth hospital, Sahlgrenska University Hospital. Population that has been selected is between 6-36 months due to the fact that the physiological development does not differ significantly with respect …
Effects of Acupuncture on Symptoms of Stable Angina
The goal of this clinical trial is to determine if a standardized 12-point acupuncture protocol will reduce pain in participants with stable angina. This study addresses the critical need to reduce persistent pain for angina. The investigators long-term goal is symptom management for diverse women and men with angina, targeting …
Transcutaneous Electrical Nerve Stimulation in Patients With Angina and Non-Obstructive Coronary Arteries
In patients with angina pectoris undergoing a coronary angiography (CAG) up to 40% do not have obstructive coronary artery disease (CAD). The majority of patients with no obstructive CAD are women with a frequency of up to 70% compared to 50% in men. These patients are diagnosed as having angina …
CMR Based Prediction of Ventricular Tachycardia Events in Healed Myocardial Infarction (DEVELOP-VT)
Fibrotic tissue is known to be the substrate for the appearance of scar-related reentrant ventricular arrhythmias (VA) in chronic ischemic cardiomyopathy (ICM). Late gadolinium enhancement cardiac magnetic resonance (LGE-CMR) has proven to be a useful technique in the non-invasive characterization of the scarred tissue and the underlying arrhythmogenic substrate. Previous …
Preventive VT Substrate Ablation in Ischemic Heart Disease
The investigators hypothesize that preventive VT substrate ablation in patients with chronic ICM, previously selected based on imaging criteria (BZC mass) for their likely high arrhythmic risk, is safe and effective in preventing clinical VT events.
DCB Under the Guidance of OCT in STEMI
Acute ST segment elevation myocardial infarction (STEMI) has a high disability mortality rate, and timely reperfusion treatment can significantly reduce the mortality of patients. Emergency PCI is the preferred strategy for STEMI treatment recommended by domestic and international guidelines. The long-term existence of stents can never completely avoid the formation …
The Role of Cardiovascular Magnetic Resonance in Patients With Non-ST- Elevation- Myocardial Infarction
The goal of this prospective study is to evaluate the role of cardiovascular magnetic resonance (CMR) in patients with suspected non-ST elevation myocardial infarction (NSTEMI). The main endpoint is the reclassification rate, defined as the number of patients in whom the information provided by pre-angiography CMR affects the revascularization strategy …
A Validation Study of Nitroglycerin Induced Acute Drop of Pd/Pa (NTG-Pd/Pa) in Clinical Practice
Hyperemia with adenosine was an elemental process in FFR examination. Adenosine injection will induce some discomfort, and increase cost expenditure. Nitroglycerine will induce an acute drop of Pd/Pa, and this lowest Pd/Pa was determined as NTG-Pd/Pa. NTG-Pd/Pa has a linear relationship with FFR value and has a good diagnostic accuracy …
