Young adults with bipolar disorder show signs of early heart dysfunction

Cardiovascular disease is the main cause of premature deaths in patients with bipolar disorder around the world. In an innovative study in young adults (aged 20–45) with researchers of bipolar disorder, they were able to detect subtle (subclinical) irregularities in the functioning of their cardiac muscles and blood pumping before starting heart failure by measuring the peak systolic load and myocardial work. The findings, published by Elsevier, indicate new therapeutic development opportunities to prevent the progress of heart failure in this endangered population.

Despite the accumulation of evidence that the risk of cardiovascular disease increases in the early stages of bipolar disorder, little studies studied heart dysfunction in the early course of the disease. This examination is the first to discover that myocardial dysfunction is already visible in patients with bipolar disorder at the age of 45 before heart failure, which suggests a possible connection with the coronary vessel dysfunction underlying the underlying dysfunction.

Using indicators sensitive to early detection of subclinical heart dysfunction before the beginning of heart failure, this study showed that both global and regional spasm peak (measuring, how much heart muscles are deforming or shortened during contraction [systole]) and myocardial work (assessment of the total work that the heart muscle performs to pump blood, taking into account how much he is shrinking and the pressure he must pump before) were impaired in the left ventricles segments in young adults with bipolar disorder compared to people of similar ages without mental disorders.

Because the Investigators Measured Regional Peak Systolic Strin and Regional Myocardial Work in Accordance with the American Heart Association (AHA) 17-SEGMENT MODEL BASED ON THE PERFUSION TERRITORIES (IE, The Left Anterior Descending, Left Circumflex, and Right Coronary Arteries), The Finkings of This Study Suggest An impared Cardiac Function in Relation to Aberrant perfusion of coronary vessels in the early course of affective affective disease.

“Since no examination had previously assessed the regional peak systolic strain and regional myocardial work in patients with bipolar disorder using the AHA 17-segment model, this test generating the hypothesis was designed to identify patterns and formulate potential hypotheses on further research on the combination of bipolar heart disorder,” Pao-Huan Chen, MD, PhD, Department, Department Department, Department, Department, Department, PHD, Department, PhD, Department, PhD, Department, PhD, Department, PhD, Department, Department, PsychiatrySchool of Medicine, College of Medicine, Taipei Medical University; and Department of Psychiatry and Psychiatric Research Center, Taiipei Medical University Hospital.

The first author of Cheng-yi Hsiao, MD, Division of Cardiology, Department of Internal Medicine and Cardiovascular Research Center, Taipei Medical University Hospital; and Taipei Heart Institute and School of Biomedical Engineering, College of Biomedical Engineering, Taipei Medical University, adds. “Although there is a lot of evidence suggesting an increased cardiovascular risk in people with bipolar disorder, we are still surprised by the findings that even in this young population with bipolar disorder intensively covers the left ventricular segments in the perfusion territories of three main coronary arteries.”

Bipolar disorder is a severe mental illness, which often manifests itself during puberty and young adulthood. Large-scale population tests and meta-analysis have revealed that in addition to experiencing mood load throughout their lives, patients have about twice as high as heart failure, which is one of the main causes of premature cardiovascular mortality in patients with two-haired disorder.

To explain the pathophysiology of heart failure in patients with bipolar disorder, future tests should examine the mechanical routes leading to coronary vessel dysfunction in this population.

After replication in future studies in various samples, the peak systolic strain and myocardial work indicators should be included in the cardiovascular assessment in patients with bipolar disorder. This assessment would be the possibility of identifying and managing heart dysfunction as soon as possible before the progress of heart failure, while putting strong foundations for the development of new therapeutic to avoid heart failure and improve life expectancy. “
