Laser That Drills Holes In The Heart Cuts Chest Pain, Hospitalizations
Using a laser to drill tiny holes in the heart to provide new blood flow dramatically reduces chest pain and cuts hospitalizations for individuals whose heart disease makes them poor candidates for surgery or angioplasty, according to a report today at the American Heart Association's 70th Scientific Sessions.

Strokes After Heart Attacks Increase Costs Of Medical Care By 56 Percent
In the first economic analysis of its kind, Duke University Medical Center researchers have found that heart attack patients who suffer from a stroke shortly after the heart attack have a 56 percent increase in their medical bills.

Casinos And Airplanes Better Equipped Than Most Doctor's Offices To Handle Cardiac Arrest
Compact devices that shock the heart into a correct rhythm to treat cardiac arrest are found on many firetrucks, police cars and even in casinos.

Robotics, The Next Frontier In Operations, Heart Surgery
Robots are being tested as a new way to help surgeons perform heart operations, according to researchers who spoke here today at the American Heart Association's 70th Annual Sessions.

Protein 'Heroes' Block Genetic Mutations
Researchers at the Weizmann Institute of Science have discovered that two repair proteins perform a truly 'heroic' act, stopping genetic mutations dead in their tracks.

Minimally Invasive Surgery Greatly Reduces Heart Bypass Deaths And Complications
A study by physicians at the University of Pittsburgh Medical Center (UPMC) has found that minimally invasive heart bypass surgery greatly reduces the number of deaths and complications in very high-risk cardiac patients who are too ill to undergo traditional bypass.

Climate Switch 118,000 Years Ago May Hold Clues To Earth's Future
A new MIT study that uncovered evidence for profound climate change at the end of the last interglacial period 118,000 years ago is a tantalizing piece of research for global- change scientists, according to a University of Colorado at Boulder researcher.

Drug Shows Promise In Keeping Cardiac Arrest Patients Alive Until They Reach The Hospital
A person who suffers cardiac arrest outside the hospital is in imminent danger of dying, especially if defibrillation fails to rapidly shock the heart into resuming normal beating.

Columbia-SUNY Team Slices Magnetic Crystal; Applications Seen For Miniaturized Optical Devices
Scientists at Columbia University and SUNY Albany have taken the first important step toward creating a microchip that combines electronics and its optical equivalent, photonics.

Polymer Coating May Help Prevent Thrombosis Following Angioplasty
According to a study by researchers at the University of Pittsburgh Medical Center (UPMC), a thin polymer coating on the inside of coronary arteries may one day prevent blood clot formation called acute thrombosis, following angioplasty.

Sexual Problems In Women Linked To High Blood Pressure
For the first time, researchers have linked high blood pressure to sexual problems in women, according to a study reported today at the American Heart Association's 70th Scientific Sessions.

Cell-Suicide-Gene Linked To Metastasis

Ribozyme Pharmaceuticals Enters VEGF Receptor Ribozyme Into Product Development
This week at the AHA Conference, researchers reported on new advances in gene therapy using VEGF to treat artery blockage.

Rare Predators Threatening Already Vulnerable East Coast Fish
Tiny, tentacled sea creatures, rarely seen drifting in the ocean, have been discovered thriving by the millions off New England's vulnerable Georges Bank, threatening valuable cod and haddock, species already decimated by overfishing in the area.

Blunt Blows From Baseballs, Hockey Pucks Cause Sudden Death In Young Athletes
Young athletes who drop dead without warning of unsuspected heart defects are widely publicized.

Death Rates Higher For HMO Patients Hospitalized For Heart Attacks
The odds of surviving a heart attack may have as much to do with a patient's health insurance policy as the hospital to which the heart attack victim is rushed or whether a cardiologist treats the patient, according to a new study presented today at the American Heart Association's 70th Scientific Sessions.

Fish Oil May Offer Better Protection Than Olive Oil Against Heart Disease
Omega 3 fatty acids, the kind found in fish oil, may offer better protection against atherosclerosis than monounsaturated fats, the kind found in olive oil, according to research at Wake Forest University Baptist Medical Center.

Moderate Alcohol Use Lowers Risk Of Deadly Second Heart Attack
Drinking moderate amounts of alcohol -- about one drink a day -- cuts the risk of a deadly heart attack in men who already had one heart attack or stroke, according to a study reported today at the American Heart Association's 70th Scientific Sessions.
