Heart attack: The test which could reveal if you are having a heart attack

-
A HEART attack happens when there is a sudden loss of blood flow to part of the heart muscle. Most heart attacks happen when the inside of one or more of the coronary arteries becomes narrowed due to the gradual build up of fatty deposits known as atheroma.


In the UK there are more than 100,000 hospital admissions each year due to heart attacks. Could a simple blood test help doctors predict the risk of heart attacks in people? If a piece of fatty material breaks off, a blood clot could form which tries to repair the damage to the artery wall. The blood clot could block the coronary artery, causing part of the heart muscle to be starved of blood and oxygen and this is when a heart attack occurs. An incredible 1.4 million people alive in the UK today have survived a heart attack. Death rates from coronary heart disease are the highest in areas of great deprivation and 42,000 people died prematurely from cardiovascular disease.


 New research suggest that by detecting the blood levels of specific proteins that heart muscles release when they are injured could help scientists predict a person’s risk of developing cardiovascular disease.
The test is now being widely used to help hospital staff diagnose heart attacks in people who come in with symptoms of chest pain.
By analysing the blood samples they are able to analyse specific proteins which are released by the heart muscle when it is damaged. 
Doctor Christie Ballantyne, senior study author and cardiology chief at Baylor College of Medicine in Houston said: “What we’re finding out is that these tests can be used in general population to give us information as to who is most likely to have a future problem, whether it be a heart attack, stroke or heart failure.”
The research involved examining a group of 8,121 people aged between 54 to 74 with no history of cardiovascular disease.
It found that when using highly sensitive troponin tests it proved especially good at predicting cardiovascular events and was able to calculate a persons 10-year risk of having a heart attack. Troponin is a protein that’s released into the bloodstream during a heart attack.
The British Heart Foundation has recently funded research into troponin testing.
Senior cardiac nurse, Christopher Allan said: “We have recently funded research into troponin blood testing that is even more sensitive and may help diagnose more heart attacks, particularly in woman, who can release lower levels of troponin.”
Doctor Ballantyne concluded: “Research in this area is leading us toward individualised care more so we can better predict who’s at risk for developing adverse cardiovascular outcomes.”

The Truth About Dealing With Heart Failure

-
A guide to reducing risks and living well even if you develop the condition Congestive heart failure is a serious illness. But it does not, as is sometimes thought, mean the heart stops ­altogether. It signifies that the muscle is damaged and can no longer pump enough blood to meet the body’s needs. This condition, which ­affects 1 in 5 adults—usually in the later years—can shorten life. But with proper treatment, people are living longer and better with heart failure. “We have more medications at our disposal today to improve quality of life for people with a weakened heart,” says Guy L. Mintz, M.D., director of cardiovascular health and lipidology at Sandra Atlas Bass Heart Hospital in Manhasset, N.Y. Here’s what to do. Coronary artery disease and heart attacks are major causes of heart failure, says cardiologist Tamara Horwich, M.D., medical director of UCLA’s cardiac rehabilitation program in Los Angeles.

Breaking Down Barriers in the Fight Against Congenital Heart Disease

-
Academic research has long been characterized by silos and protective instincts. A new crop of fresh-thinking physician scientists are turning that model on its head, and the results are saving little hearts. More than 1 in every 110 babies is born with some form of congenital heart disease. CHDs are the most common birth defect, in fact. Clinicians have made great strides in improving care for these children, and even individuals with severe diseases may now live well into adulthood. However, not all survive and many still experience significant complications.   “As a doctor in a pediatric cardiac ICU, we know there are things we want to do better,” says Michael Gaies, M.D., a cardiac intensivist and director of quality at the Congenital Heart Center at Michigan Medicine’s C.S. Mott Children’s Hospital. “We believe we can improve care for kids recovering from heart surgery if we can better control certain parts of the post-operative journey.” The problem? Data, or rather,

Cerebrovascular Disease: A Serious Complication After Allogeneic Hematopoietic Stem Cell Transplantation

-
A study published in the  International Journal of Hematology  found that the incidence of cerebrovascular disease (CVD) was approximately 10 times higher in patients after  allogeneic hematopoietic stem cell transplantation (HSCT) compared with the general Taiwanese population. Moreover, CVD was associated with the number of high-dose cytarabine courses given. The researchers retrospectively evaluated clinical data from adult patients who underwent HSCT at an Asian tertiary medical center between January 2003 and December 2015. The study aimed to estimate CVD incidence, identify associated host-related and transplant procedure-related risk factors, and measure clinical outcomes (overall survival [OS] and disease-free survival [DFS]). Data from 459 adult allogeneic HSCT recipients were assessed. Of this patient cohort, 4.4% (20/459) developed post-transplant CVD, 2.4% (11/459) had intracranial hemorrhage (ICH), and 2.2% (10/459) had cerebrovascular infarction. Median follow-up wa
