Active clinical trials for "Chest Pain"

Poststernotomy pain is a complication of cardiac surgery. Poorly controlled pain is associated with myocardial ischemia, cardiac arrhythmias, hypercoagulability, pulmonary complications, and increased rates of delirium and wound infection. The transverse thoracic muscle plane (TTMP) block is a novel plane block that provide pain for sternotomy. The aim of this study was to evaluate the analgesic effect of ultrasound guided TTMP block in patients undergoing open heart surgery.

As part of the planned implementation of a new clinical pathway using hs-cTnI, the investigators will measure patient outcomes and clinical processes in a real-world scenario throughout an integrated health system across 9 emergency departments (ED).

Non-cardiac chest pain (NCCP) is common and has substantial impact on patients' psychological wellbeing, quality of life and healthcare use. Although cardiac diagnosis is 'ruled out', many patients think they have an undetected cardiac disease (i.e. they suffer cardiac anxiety) as no other explanation is offered. They therefore avoid activities that they believe might be harmful to their heart, leading to greater ill-health, and increased healthcare use and societal costs. Targeting cardiac anxiety with psychological interventions might break this vicious circle and improve patient outcomes. Patients need to evaluate the way they perceive and handle their chest pain, which can be done with cognitive behavioral therapy (CBT). The aim of this study is therefore to evaluate the short- and long-term effects of an Internet-delivered CBT (I-CBT) program on psychological distress and other patient-reported outcomes in patients with NCCP. A second aim is to explore factors related to implementation of I-CBT in clinical care. The study has a randomized controlled design comparing I-CBT with Internet-delivered information program. Quantitative methods will be used to evaluate the effectiveness of the I-CBT program. Implementation issues will be evaluated from the perspectives of patients, healthcare professionals and policymakers using qualitative methods.

This is a prospective randomised clinical trial performed in a single center at Hospital Universiti Sains Malaysia (USM), Kelantan, Malaysia. Participants will be randomly allocated into either the empirical group or guided group for 8 weeks.The effectiveness in relieving chest pain (frequency and severity) will assessed after 2 weeks and 8 weeks of therapy with Gastroesophageal Reflux Disease Questionnaire (GERDQ) and Quality of Life Reflux and Dyspepsia (QOLRAD) questionnaire, and visual analogue scale (VAS) (score 1-10).

This pilot randomized controlled trial (RCT) aims to test the feasibility and effectiveness of a guided internet-delivered cognitive behavioural therapy intervention in the treatment of cardiac anxiety and fear of body sensations in patients with non-cardiac chest pain. The control group will receive care-as-usual.

Our research will examine a chest pain care strategy, called the HEART pathway, which is designed to correctly identify Emergency Department patients at high-risk for cardiovascular events, likely to benefit from further testing, and patients at very-low-risk for cardiovascular events, who may be safely discharged home. By using an individual's risk assessment to determining testing, we hope to improve the quality and efficiency of the care delivered to Emergency Department patients with chest pain. Our study will determine if the HEART pathway, which combines a clinical decision rule, the HEART score, and two serial troponin measurements, will reduce stress testing and cardiovascular imaging, decrease hospital length of stay, and reduce cost compared to usual care, while maintaining safety.

This study will use myocardial contrast echocardiography performed during a continuous intravenous infusion of Definity microbubbles (Perflutren lipid microbubbles) to determine if dexmedetomidine (an intravenous central sympatholytic drug) can reverse all the cardiovascular effects of low-dose intranasal cocaine-including vasoconstriction in the coronary microcirculation-both in cocaine-naïve and non-treatment seeking cocaine-addicted subjects.

The purpose of this study is to compare the effectiveness of standard medical therapy versus usual care in women with chest pain, coronary endothelial dysfunction and unblocked coronary arteries. Coronary endothelial dysfunction (CED) is a condition in which the layers of cells around the heart do not function properly and is believed to be key factor in the development of atherosclerosis (fat deposits in arteries). In addition, CED is associated with an increased risk for future cardiovascular events, such as heart attack and stroke. A coronary angiogram allows physicians to see if any of the arteries in the heart are blocked, usually by fatty plaque. In many instances, angiograms in women experiencing chest pain do not show evidence of coronary disease (free of significant plaque build-up). Currently, there is no standard of care treatment plan for patients with normal coronary arteries, despite symptoms of chest pain, and as a result these patients may not receive medical treatment. However, these women often return to their physicians more than once with chest pain and go through a similar battery of tests.

The Distal Radial Access (DRA) to the coronaries has emerged recently. It's done via the distal radial artery in the radial fossa, which is known as the snuff-box. The rationale of conducting this research is to assess this new access advantages and disadvantages, in comparison with the standard conventional forearm radial access and examine if it's worthy to be a future alternative method for coronary angiography. It aims to randomly compare between the new distal radial access via the snuffbox and the conventional forearm radial access for percutaneous coronary angiography and angioplasty procedures. The objectives of comparing both procedures are to analyze the frequency of complications in terms of occlusion, arterial spasm, hematoma, and to weigh accesses effectiveness in terms of time and attempts to puncture, crossover rate, procedure duration, hemostasis time, and convenience of the patients and operators. Candidates for coronary angiography are being randomized into the interventional group to undergo the angiography through the distal radial artery as the access site, or the control group accessing through the radial artery in the forearm. Procedural and post procedural outcomes and complications are being reported while patients are in hospital. All patients undergo doppler ultrasonography within 24 hours after the procedure.

Background: Noncardiac chest pain (NCCP) affects 200,000 new cases annually in USA. It is associated with poor quality of life and high health care expenditure of 8 Billion Dollars a year. Gastroesophageal Reflux Disease(GERD), esophageal motility disorders, and psychological issues may cause NCCP. The mechanism(s) for pain continue to be explored and include central and peripheral hypersensitivity, and mechanophysical abnormalities. Treatment of NCCP has focused on relieving visceral hypersensitivity through pain modulators, such as tricyclics, trazodone, or adenosine receptor antagonist, theophylline. Typically, only 40-50 % respond and clearly there is a large unmet therapeutic need. Cannabis is felt to be beneficial for vomiting, diarrhea and intestinal pain. The main component of Cannabis acts through specific receptors, that are located primarily on central and peripheral neurons (including the enteric nervous system) and myenteric plexus where they modulate neurotransmitter release. Activation of these receptors reduces excitatory enteric transmission and may improve esophageal hyperreactivity and hypersensitivity, the hallmarks of NCCP. STUDY PROTOCOL: The investigators will randomize 40 subjects with non-cardiac, non-reflux chest pain to receive dronabinol (5 mg Bid), or placebo for 4 weeks. Chest pain symptoms and esophageal sensorimotor properties will be assessed at baseline and at 4 weeks using symptom diary and impedance planimetry. The primary outcome measure will be the frequency of chest pain episodes. Secondary outcome measures include improvement in esophageal sensory thresholds, reduced reactive contractions, frequency, amplitude, area under the curve, and global improvement of symptoms. HYPOTHESIS: Cannabinoids decrease esophageal hypersensitivity and ameliorate chest pain in NCCP patients, when compared to placebo. AIM: To perform a randomized double blind study to investigate the effects of Dronabinol, a CB1 and CB2 agonist, in the treatment of patients with NCCP and examine its mechanism of action.
