Let’s welcome 2010 with some heart(y) news!
Varenicline safe and effective in cardiovascular disease
The smoking cessation drug varenicline is safe for people with increased heart rate and elevated blood pressure, a recent study reported.
According to lead author Dr Nancy A Rigotti of the Massachusetts General Hospital in Boston
“We wanted to answer the question of whether varenicline is effective and safe in patients with stable cardiovascular disease. The answer is a very clear yes. It works and it’s safe from a cardiovascular perspective. There is no reason that patients with stable heart disease who would otherwise be appropriate for varenicline shouldn’t take it. In fact, it’s quite effective and is something that really should be offered to these patients.”
Gains from losses
Proper diet and physical exercise can help shed off some kilos. However, it is always a big challenge to keep off weight lost. Thus, people are discouraged by the so-called “yoyo effect.” However, weight lost and then gained again is not all for nothing. During the process of losing weight, your heart and your blood vessels actually benefit from the diet and the exercise.
According to researcher Lisa de las Fuentes of Washington University School of Medicine in St. Louis:
“This is just reinforcing that it doesn’t matter how you get there. It’s just that you actually lower the amount of calories you are consuming, expend more calories through exercise, and achieve weight loss.”
HHS Delivers the Nation’s First Health Security Strategy
US Secretary of Health and Human Services recently released The National Health Security Strategy, the country’s first comprehensive strategy focused on protecting people’s health during a large-scale emergency.
National health security means that the nation and its people are prepared for, protected from, and resilient in the face of health threats or incidents with potentially negative health consequences such as bioterrorism and natural disasters. The strategy provides a framework for actions that will build community resilience, strengthen and sustain health emergency response systems, and fill current gaps.
The strategy sets priorities for over the next four years
Chemotherapy-induced heart damage reversed in rats
Chemotherapy in the treatment of certain cancers can cause irreversible damage to the heart. However, there is hope that this damage may be reparable after all. In a study in lab rats, researchers at xxx were able to repair chemotherapy-induced heart tissue damage using cardiac stem cells (CSCs) taken from the undamaged part of the animal’s heart.
According to study author Dr. Piero Anversa, one of the study’s authors and director of the Center for Regenerative Medicine in the Departments of Anesthesia and Medicine and Cardiovascular Division at Brigham & Women’s Hospital in Boston, Mass.
“We repopulated the heart muscle with CSCs and this intervention rescued the heart…This approach may be used in patients affected by cancer who received chemotherapy drugs. Cardiac stem cells could be collected before chemotherapy, then expanded and stored. If heart failure occurs, the patient may receive his/her own cardiac stem cells to regenerate damage.”
