A study conducted among diagnosed coronary artery disease patients by the researchers at the Intermountain Healthcare, Salt Lake City shows twice or double death risk in those individuals who develop depression subsequent to coronary artery disease compared with non-depressed patients. This study also shows a bi-directional relationship between heart disease and depression. Likely development of depression with the presence of heart disease and worse outcome for heart disease in individuals with depression. The depression risk factor is independent of when the coronary artery disease patient was diagnosed with depression. Authors of the study say their findings show the importance of depression screening and subsequent treatment even years after the patient was diagnosed with coronary artery disease.
Researchers had conducted for an average 10 year follow-up study on 24,138 patients and their study shows post-coronary artery disease, depression was a bigger and independent predictor of death after evaluating other risk factors such as age, diabetes or blood sugar levels, heart failure, kidney failure, high blood pressure and having a heart attack or stroke. Researchers used angiographies report determine coronary artery disease and International Classification of Diseases codes, or ICD codes to determine subsequent depression in the patients.
The study could not explain the reasons for enhanced death risk with depression. But researchers say heart disease patient with depression may not take his regular medications, may not eat a healthy diet and may not be doing daily exercise. Lead author of the study was Dr. Heidi May, PhD, a cardiovascular epidemiologist, Intermountain Medical Center Heart Institute, Salt Lake City, Utah, United States. The study findings were published 26 July 2017 in the European Heart Journal - Quality of Care and Clinical Outcomes. Title of the article was "The association of depression at any time to the risk of death following coronary artery disease diagnosis".
The World Health Organization (WHO) says more than seven million individuals are dying worldwide every year due to cardiovascular diseases and it is a leading cause of death. A study done by researchers from the University College London and the Imperial College London shows a protective effect on coronary artery disease CAD (or coronary heart disease, CHD or atherosclerosis), a type of cardiovascular diseases (CVD), with high levels of iron. That means higher risk for heart diseases with low levels of iron. They came to the above conclusion after analyzing genetic data of 48,000 people. They also say gender and age factors can affect the assessment of CVD risks with iron levels. Authors of the study say the risk for further heart attacks can be reduced in heart attack patients with low iron levels by giving them iron tablets. Lead author of the study was Dr. Dipender Gill. The study findings were published on July 6, 2017, in the journal Arteriosclerosis, Thrombosis and Vascular Biology. Title of the article was "The Effect of Iron Status on Risk of Coronary Artery Disease".
