A study done by researchers at Samsung Medical Center, Seoul shows coronary artery stent operation association to lower risk of stroke and heart attack among type 2 diabetes (T2D) patients who maintain good blood sugar or glucose levels over the years. Earlier studies show no relief to major cardiovascular events or improvement to damages in tiny blood vessels with intensive sugar or glucose control. Improvements to major arteries with intensive sugar control is not clear. But current study results show intensive sugar control after heart catheterization or PCI can improve outcomes of any healthcare intervention.
Percutaneous cardiac intervention (PCI) procedure is conducted among cardiovascular or heart disease patients to clear the blocked coronary artery. After clearing the blocked artery, a stent (a supportive mesh tube) will be placed inside the coronary artery. The researchers studied 980 patients with type 2 diabetes (T2D) who took percutaneous cardiac intervention (PCI). They conducted follow up studies for over seven years. During the study period, researchers collected blood sugar levels (HbA1c) of the participants and compared it with patient's health factors to diseases such as heart attack, stroke, death and repeat catheterizations.
The researchers defined good blood sugar or glucose control with the HbA1c value below 7.0 and poor blood sugar or glucose control with the HbA1c value equal to or over 7.0. Researchers found that risk of all bad outcomes was 25 percent lower in those patients maintaining good HbA1c levels when compared with those individuals having bad HbA1c levels. In statistical matched comparison technique, 37 percent of the patients with poor sugar control had bad outcomes such as stroke, heart attacks compared with less than 28 percent of the patients with good blood sugar or glucose control.
The researchers say more study is required to conclude that type 2 diabetes (T2D) patients could be benefited with long-term clinical outcomes in those individuals who follow strict blood sugar control after coronary artery stent operation. Author of the study was Dr. Joo-Yong Hahn, Samsung Medical Center, Seoul and the study findings were published on April 3, 2017, in the Circulation: Cardiovascular Interventions.
An observational long-term study done by researchers at Johns Hopkins shows risk reduction to heart attacks and strokes with daily exercise and good vitamin D levels in the body of an individual. Their study involves more than 10,000 American adults spanning over 20 years. The study includes analyzing surveys and health records of the individuals. Their study shows vitamin D deficiency and not performing recommended physical activity is common in patients with strokes and heart attacks. But researchers are not saying that vitamin D and daily exercise are indicators for good heart health. This study was not intended to show cause and effect relationship between them.
Recommended daily vitamin D requirement is 600 to 800 International Units per day. Health care professional should check patients vitamin D levels if the patient is suffering from seasonal depression, bone diseases or with obesity. The study findings were published on April 1st, 2017 in the Journal of Clinical Endocrinology & Metabolism.
