After Heart Attack, Growth Factor Improves Scar Quality and Heart Function in Pig Study

Composed primarily of collagen and strengthened with cross-linked fibers, scar tissue that forms after a heart attack doesn ’t contract as well as healthy muscle tissue. It can therefore compromise the organ’s ability to pump blood, which may lead to heart failure, arrhythmias, and sudden cardiac death. Scientists who developed a therapy that targets such scar formation, or fibrosis, recently brought their strategy a step closer to the clinic. After demonstrating its effectiveness in rodents, their latest work—a randomized, double-blinded pig study—validates the approach in a large-animal model.

Atrial fibrillation is the most common sustained cardiac arrhythmia in the general population. In western countries with aging populations, atrial fibrillation poses a significant health concern, as it is associated with a high risk of thromboembolism, stroke, congestive heart failure, and myocardial infarction. Thrombi are generated in the left atrial appendage, and subsequent embolism into the cerebral circulation is a major cause of ischemic stroke. Therefore, patients have a lifetime risk of stroke, and those at high risk, defined as a CHA2DS2-VASc2 (congestive heart failure, hypertension, age>75 years, diabetes mel...

ConclusionRobotically assisted Heller myotomy and POEM are safe and efficacious treatments for achalasia with lower rates of technical complications compared to laparoscopic Heller myotomy. With the advancements in endoscopic instruments and robotic surgery, POEM and robotically assisted Heller myotomy should be considered in the treatment of achalasia and esophageal dysmotility disorders.

AbstractThe use of cocaine constitutes a major health problem. Cocaine use is associated with acute and chronic complications that might involve any system, the most common being the cardiovascular system. The precise incidence of cocaine-induced cardiomyopathy remains mysterious and probably underreported. Cocaine use should be considered in young patients presenting with chest pain or heart failure without other underlying risk factors. Cocaine-related cardiovascular complications can be acute or chronic and include ischemic and non-ischemic events. Frequent cocaine users have a seven-fold higher risk of myocardial infar...

NEW BRUNSWICK, NJ, May 27, 2020 — The Janssen Pharmaceutical Companies of Johnson &Johnson today announced that the U.S. Food and Drug Administration (FDA) has granted approval for a new pediatric formulation of SIRTURO® (bedaquiline). SIRTURO® is now indicated for use as part of combination therapy in the treatment of adult and pediatric patients (5 years and older and weighing at least 15 kg) with pulmonary multidrug-resistant tuberculosis (MDR‑TB). In the U.S., the medicine should be reserved for use when an effective treatment regimen cannot otherwise be provided. This indication received accelera...

Conclusions BBs differ within the class in so many ways that it is not only logical but also practical for real-life clinical practice that experts in the field make a list of the compelling indications for individual BBs. Time has come to incorporate our knowledge about BBs into a new approach of presenting these useful and very individual drugs. PMID: 32418526 [PubMed - as supplied by publisher]

Authors: Hung MY, Kounis NG, Lu MY, Hu P Abstract In coronary artery spasm (CAS), an excess coronary vasoconstriction causing total or subtotal vessel occlusion could lead to syncope, heart failure syndromes, arrhythmic syndromes, and myocardial ischemic syndromes including asymptomatic myocardial ischemia, stable and unstable angina, acute myocardial infarction, and sudden cardiac death. Although the clinical significance of CAS has been underrated because of the frequent absence of symptoms, affected patients appear to be at higher risk of syncope, serious arrhythmias, and sudden death than those with classic Heb...

Authors: Chen T, Li J, Xu Q, Li X, Lv Q, Wu H Abstract Giant coronary artery aneurysm (CAA) is a rare disorder, defined as coronary artery dilatation, in which the diameter of the coronary artery exceeds more than 1.5 times of its normal size. The most common cause of CAA is coronary atherosclerosis for adults and Kawasaki disease (KD) for children and adolescents (especially for the giant CAA that occurred in adolescence). CAA complications include thrombus, acute myocardial infarction (AMI), vasospasm, rupture, ischemia, heart failure, and arrhythmia. So, antithrombotic therapy is crucial for patients with giant ...

In conclusion, longitudinal change in sST2 but not BNP was associated with incident MACE in asymptomatic, initially event-free patients in the community. Further work is required to evaluate the clinical utility of change in sST2 in risk prediction and event monitoring in this setting. PMID: 32347644 [PubMed - as supplied by publisher]

Conclusion: A history of hypothyroidism and the degree of TSH elevation seem to guide the management of hypothyroidism in patients with AMI. The clinical effect of correcting hypothyroidism in this setting requires further evaluation. PMID: 32353935 [PubMed - in process]
