Scientists have created a new form of collagen-based blood vessels made from human donor tissue. It has numerous uses like blood vessel-like grafts in coronary artery bypass and access points for patients who need kidney dialysis. tonus fortis pret
The grafts appear to be strong enough to be stored for a year. What this means is hospitals could make them in ahead of time to be used when surgeons need them. hallu forte
Researchers created two types of blood vessels, one is 6 millimeters in diameter and the other is 3-4 millimeters in diameter. While there hasn’t been any human testing, researchers have found success in animal testing. Baboons had an 88% success rate in large vessels, and dogs had an 83% success rates with blood vessels. hallu forte
There has been no testing on humans yet, this study should lay the foundation. About 500,000 patients a year could benefit from this discovery. Blood vessels around the heart could be replaced when they clogged with plaque. Though, the artificial vessels may be used as a last resort when it becomes available for human use, but one day they can become the norm. Kattintson ide
A new study shows heart failure treatment works better in women.
The treatment is called cardiac resynchronization therapy with defibrillator. The defibrillator is an implantable device that helps coordinate the action of the left and right heart ventricles by delivering a small electric shock to the heart. When the device senses abnormal heart rhythms, it shocks the heart back to a normal beat.
In this study, women treated with cardiac resynchronization therapy had a 70% reduction in heart failure while men only had a 35% reduction.
Heart failure occurs when the heart cannot pump enough blood throughout the body. A common cause of this in women is dyssynchrony, where the heart ventricles do not contract simultaneously. The device in this study is the perfect solution to this problem. This and the fact women generally have smaller hearts than men are the main reasons cardiac resynchronization therapy works better in women.
However, to accurately make this conclusion, a new study must examine men and women with the exact same heart disease and no other outlying conditions to influence the outcomes. So for now, all there is strong evidence that women react more positively to heart failure treatment than men.
The cost of heart disease treatment is expected to triple by the year 2030. Over the next 20 years, experts predict the overall cost of treatment will increase to $545 billion thanks to the aging baby boom population.
Despite much advancement in the field of heart disease during the past 50 years, the same cannot be said for the next twenty. Leading researchers say do not expect medical breakthroughs on the same scale as the past years. In other words, more people are getting older and developing heart disease and technology cannot keep up.
According to the numbers, more than 40% of all Americans or 116 million people will have heart disease in 2030. The biggest increases will be stroke at an estimated 24.9% and heart failure at an estimated 25%.
The only way to combat this prediction is to prevent as much heart disease as possible, right now. A panel of experts suggested that the U.S. healthcare system should focus their resources on prevention and early intervention on risk factors for heart disease. Fighting heart disease today is much cheaper than paying the price in the future.
High cholesterol has been a constant challenge in America. Even if your doctor prescribes drugs to lower your cholesterol, that alone isn’t enough. To lower your cholesterol, you have to change your entire lifestyle and diet. Sounds like a tough solution. Luckily, here are 3 tips to help you along.
- Eat heart-healthy foods – Be sure to eat five to nine servings of fruits and vegetable everyday. Not only do they contain antioxidants to boost health, but they also curb appetite. A two-for-one benefit is a surefire way to get that cholesterol down.
- Fish – They are low in saturated fat and high in omega-3 fatty acids. Omega-3 fatty acids help lower a type of fat in the blood, lower cholesterol, and slow the growth of plaque in arteries. So be sure get your double dose of fish a week.
- Work out without exercise – The word exercise can scare many people. So instead of exercise, try some physical activities that really get the heart going. Gardening, dancing, even chores can be really good for the heart.
There are plenty of other tips out there. If you know any, comment on this post!
Researchers have found high systolic blood pressure in middle-aged women is a large risk factor in developing heart disease. They also claim reducing high blood pressure in older women can help them reduce the risk of heart disease.
Three risk factors make up 85% of reversible risk for heart disease in women and men. They are high systolic blood pressure, high cholesterol, and smoking. Systolic blood pressure is said to be the most important one. So by reducing high systolic blood pressure early on, it may help prevent heart disease later on. The study also states women all over the world could benefit from these findings.
The study looked at people from 11 different countries throughout Europe, Asia, and South America. 9,257 adults (average age 57, 47% women) were studied for 11 years. Researchers analyzed individuals for absolute and relative risk for cardiovascular disease associated with systolic blood pressure. What they found out is that older women with high systolic blood pressure were at a greater risk for heart disease.
What this means for physicians and healthcare professionals everywhere are that they need to be more aggressive in their detection, treatment, and prevention of high systolic blood pressure in women everywhere.
People who regularly drink a large amount of alcohol daily are at more risk for developing a dangerous irregular heart rhythm (atrial fibrillation) than nondrinkers.
Atrial fibrillation is a life-threatening irregular heart rhythm. It causes episodes of fast, uneven heartbeats that can result in chest pains, shortness of breath, and an increased risk of heart failure and stroke. Daily, large consumption of alcohol can lead to this condition.
A large amount of alcohol is categorized as more than 2 drinks a day for men and more than one and a half drinks a day for women. Before this new study, there has not been consistent proof of the link between habitual drinking and atrial fibrillation.
The new study states an 8% increased risk for each drink containing 10 grams of alcohol. Basically, one drink per day increases the chance of developing atrial fibrillation by 8% and two drinks a day raises the risk by 16%. While the study does not state how alcohol consumption affects atrial fibrillation risk, one researcher says it’s best just to avoid alcohol if you’re worried about atrial fibrillation at all.
Researchers have found two new genes associated to heart disease. These new findings can lead to better detection and prevention of heart disease for those at risk in some.
DNA of 12,400 people with coronary artery disease (CAD) and 7,400 people without CAD were analyzed. To further identify genes closely linked to heart disease, researchers also compared 5,800 CAD patients with a history of heart disease to 3,600 patients with no such history. This led to the discovery of ADAMTS7.
ADAMTS7 is a gene connected to the buildup of plaque in the arties of the heart. The same enzyme found in people with blood type O had some protection against heart attack, even with arterial plaque. This doesn’t mean people with blood type O shouldn’t worry about heart disease, other factors like smoking and high blood pressure still factor into heart disease risk.
With the identification of these gene markers, and future discoveries, the future looks bright. Fighting heart disease will become much easier due to treatments targeting a patient’s individual heart disease risk.
The American Heart Association has called for reduction in salt consumption. They urged for the public, health professionals, the food industry, and the government to hear their plea. The high amounts of sodium found in everyday foods is a major health concerns for Americans everywhere
Sodium has many adverse effects on the body. As salt consumptions goes up, so does blood pressure and risk for other health problems. The heart, kidneys, and blood vessels suffer as well. So the American Heart Association proposes a goal to improve overall cardiac health by 20% and reduce deaths from cardiovascular disease and stroke by 20%. To achieve this goal, the organization has suggested to reduce overall salt consumption to 1,500 mg/daily as one of the guidelines.
Not only does a reduction of salt consumption improve the overall health of the American public, it could also potentially save $24 billion in medical costs a year.
Educating the public and getting the food industry to add less salt to food are the keys to a healthier America.
Spending hours in front of the TV or the computer may hurt the heart.
A new study followed 4,500 adults over the age of 34 for an average of 4.3 years. Researchers asked participants how much time they spent on average looking at a screen voluntarily (not required by work or school). Then researchers asked how much physical activity, both at work and outside of work. They linked the survey results to hospital admissions from 1981 through December 2007.
People who spent more than two hour a day in front of a screen had 125% greater risk of experiencing cardiovascular events and 48% risk of dying for any reason compared to individuals who spend less time in front of a screen.
Even more surprising was the fact that the risk did not drop factored in other variables like diabetes, high blood pressure, smoking, body weight, socioeconomic, or even regular exercise routine. So what experts recommend is cutting down on sedentary behavior like sitting down on the couch and watching TV.
Over 20% of patients with implanted cardiac defibrillators (ICD) are unlikely to benefit from it. An implanted defibrillator is a device implanted into a person that shocks the heart out of dangerous rhythms (arrhythmia).
Past studies have indicated a similar conclusion, so an investigation was launched to determine the percentage of patients actually benefitting from an ICD.
For the study, about 111,707 patients with ICDs were examined. About 25,145 or 22.5% of devices implanted in patients who did not meet the criteria for ICD use. These patients tended to be older and have other serious health problems. What the researchers also observed is these patients were more likely to die in the hospital, have a greater chance of complications, and have longer hospital stays than patients who did fell within the guidelines.
The main reason for the overuse of ICD is doctors. Doctors may choose to ignore the guidelines because they feel the ICD is needed despite the guidelines or lack the knowledge of the guidelines. Yet, there are many risks to improper implantation. So be sure to ask your doctor if an ICD is really needed or get a second opinion.
