The new procedure was coronary angioplasty, a far less invasive and expensive procedure than coronary bypass surgery that is now performed over a million times each year in the U.S. alone, while saving countless lives.

Nissen's studies use a technique called intravascular ultrasound (IVUS), which measures the volume of plaque in a coronary artery using an ultrasound probe inserted through a catheter.
In 1988, the American doctor Randolph Byrd recruited some born-again Christians to pray outside a San Francisco coronary care unit for a randomized group among 400 patients.
Give a group of cardiologists high-quality coronary angiograms (a type of radiograph or x-ray) of typical patients and they will disagree about the diagnosis for about half of the patients.
Dr. Robert Bonow, chief of cardiology at Northwestern University's Feinberg School of Medicine, notes that about 10 percent of study participants with a positive test had normal coronary arteries, and 17 percent of those with a normal test had coronary disease.
Patients with a positive coronary CT scan would then require a cardiac catheterization, with possible angioplasty and stent placement.
To take just one example, from a public health perspective, it makes little sense to focus on the miniscule elevation in breast cancer risk associated with light-to-moderate alcohol consumption, when moderate alcohol intake has been shown to have a beneficial effect on coronary heart disease, a much more common condition.

From 1999 through 2001, two of the 175 patients on whom Isom performed a simple coronary artery bypass graft (CABG) died, a 1.14 percent mortality rate, according to figures recently released by the New York State Department of Health.
The 55-year-old left hospital over the weekend following an angioplasty - a process in which a coronary artery is widened - on Friday.
They monitored how volunteers' arteries coped with the fatty drink and checked for calcium deposits in their coronary arteries, a sign of heart disease.

Dr Chris Jones, a cardiologist and medical director of NHS Wales, said coronary heart disease was a largely preventable condition, which increased in risk with age.
The good news is that there is also a CT scan available to detect fatty deposits that constitute soft plaque, called a Coronary CT Angiography (CTA).

The New England Journal study, involving 1, 400 adults over a 2.5 year period showed that the rate of heart attack 1 month after a negative coronary CT was less than 1 percent, showing that it is a safe test for patient discharge from the ER.
Cina also said Friday that coronary artery disease was a contributing cause to Khan's death, because the autopsy showed one of his major coronary arteries was 75% blocked.

It should be noted that if you are older, have a history of coronary disease and previously placed cardiac stents (high risk), the coronary CT angiogram would not be an appropriate test as a triage tool in the ER.
Additional tests may include a nuclear stress test to assess for blockages in the coronary arteries, and if positive, a cardiac catheterization, an invasive test which involves threading a thin wire into the heart to assess for blockages in the coronary arteries as well.
Doctors often gloss over a key question for assessing a person's risk for coronary heart disease, according to a new study: What is the patient's family history of cardiovascular illness?
In December, Philip spent four nights, including Christmas Eve and Christmas, in hospital for treatment of a blocked coronary artery.
They also had an 86% reduced risk of having coronary heart disease and a 46% reduction in the risk of developing cardiovascular disease, according to the researchers.
Before the bladder infection, which he initially contracted during events marking the queen's diamond jubilee, he spent four nights in a hospital over the Christmas holiday last year for treatment of a blocked coronary artery.
Since ER crowding and boarding of admitted patients is currently a growing problem, the coronary CT scan may certainly allow for accomplishing this goal in a safe and efficient manner.
Kelly had a significant degree of coronary artery disease and that this may have played some small part in the speed of death but not a major cause of death, he added.
Other recent studies suggest the significant mortality benefits of running may diminish or disappear at mileage exceeding 30 miles a week and other, very small studies have shown elevated levels of coronary plaque in serial marathoners a problem that rigorous exercise theoretically could cause.
In fact, many instances of coronary artery syndrome develop after a plaque ruptures.
Today, even a completely blocked coronary artery can sometimes be opened with PCI.
His coronary arteries were hard as a rock and filled with calcium.
