Genetic therapy heals damage caused by heart attack

Researchers from King's College London have found that therapy that can induce heart cells to regenerate after a heart attack. Myocardial infarction, more commonly known as a heart attack, caused by the sudden blocking of one of the cardiac coronary arteries, is the main cause of heart failure, a condition that now affects over 23 million population in the world, according to the World Health Organisation.

CONCLUSION: Typhaneoside regulates IL-6 and TNF-α as well as MMP-2 and MMP-9 in rats with heart failure after myocardial infarction. Typhaneoside can improve cardiac morphological structure and myocardial remodeling and enhance heart function. It may mediate autophagy inhibition in the cardiomyocyte anoxia/reoxygenation (A/R) pathway through the PI3K/Akt/mTOR autophagy transduction pathway.

The objective of this study was to investigate the vulnerability of hearts with aging, LVH, diabetes, and pregnancy to ischemic insult and their response to pacing postconditioning- (PPC-) induced heart protection. Methods: Hearts isolated from aged, spontaneously hypertensive and diabetic male and female rats and hearts from pregnant female rats (n=8 per group) were subjected to coronary occlusion followed by reperfusion using a modified Langendorff system. Hemodynamics data were computed digitally, and cardiac damage was accessed by measurements of infarct size and cardiac enzyme release. Results: There were no...

THURSDAY, June 13, 2019 -- Radiation treatment for lung cancer can help extend lives, but it might also raise a patient's odds for heart attacks and heart failure, a new study shows. Many patients may have no choice but to accept the risk: For about...

Authors: Schulz H, Karrasch S, Bölke G, Cyrys J, Hornberg C, Pickford R, Schneider A, Witt C, Hoffmann B Abstract The second part of the DGP-statement on adverse health effects of ambient air pollution provides an overview of the current ambient air quality in Germany and its development in the past 20 years. Further, effects of air pollution on the cardiovascular system und underlying pathophysiological mechanisms are introduced. Air pollutants form a highly complex and dynamic system of thousands of organic and inorganic components from natural and anthropogenic sources. The pollutants are produced locally o...

Reductions in gut microbiota‑derived metabolite trimethylamine N‑oxide in the circulation may ameliorate myocardial infarction‑induced heart failure in rats, possibly by inhibiting interleukin‑8 secretion. Mol Med Rep. 2019 May 27;: Authors: Li X, Sun Y, Zhang X, Wang J Abstract Myocardial infarction (MI) is a common cause of chronic heart failure (HF). Increasing evidence has revealed that trimethylamine N‑oxide (TMAO), a gut‑microbiota‑derived metabolite, contributes to the pathogenesis of cardiovascular disease by promoting inflammation. Elevated levels of circulating TMAO ha...

Light chains are proteins produced by plasma cells, also called light chains kappa and lambda, are tied together with other proteins (heavy chains) to form the intact immunoglobulins or antibodies. Recent studies have shown a possible role of combined free light chains (cFLC) as an inflammatory marker in patients with chronic heart failure (HF). HF is a significant contributor to overall mortality in the community, but often patients with chronic HF also have chronic renal failure, which could alter the concentration of cFLC.

ConclusionsCompared with the unvaccinated ICU survivors, the influenza vaccinated ICU survivors had a lower 1-year risk of stroke and a lower 1-year risk of death, whereas no substantial association was observed for the risk of hospitalization for myocardial infarction, heart failure, or pneumonia. Our findings support influenza vaccination of individuals aged  ≥ 65 years.

AbstractBackground and ObjectiveAtrial fibrillation, the most frequent form of arrhythmia, affects 5 –15% individuals aged> 80 years. Stroke is a major risk for atrial fibrillation patients. The benefits of anticoagulant therapy clearly outweigh the risk of hemorrhage, even in the elderly. Despite the efficacy of warfarin, many eligible patients receive no prophylactic antithrombotic therapy. New generation oral anticoagulants compare favorably with vitamin K antagonists in the prevention of thromboembolic events and hemorrhage. These new agents are likely to influence the prescribing habits of anticoagulants in a...
