Study Finds Strain Echo Good Evaluator for Hypertrophic Cardiomyopathy Risk Assessment

Results convey hope for common condition that often goes undetected and results in sudden cardiac death

June 13, 2016 – After following a large sub-set of patients, researchers found that by using strain echocardiography they could accurately predict which patients were likely to have complications from hypertrophic cardiomyopathy (HCM). This is important because HCM is common, but often undetected, and one of the leading causes of sudden cardiac death in young adults.

“HCM is the most common inherited cardiac condition with several disabling and life-threatening complications. Global longitudinal strain was able to independently predict key outcomes in HCM and therefore has the potential to become an essential tool in HCM risk assessment,” said Hongyun Liu, M.D., of the Johns Hopkins HCM Center of Excellence, Baltimore.

Conventional and strain echocardiography were performed in 400 HCM patients who were followed for 37 months to obtain the necessary data. Strain echocardiography is an advanced but growing cardiovascular diagnostic technique that is a sensitive and powerful way to assess patient outcomes.

Researchers on the study, “Global Longitudinal Strain Independently Predicts Outcomes in Hypertrophic Cardiomyopathy,” included Liu, Iraklis Pozios, Bereketeab Haileselassie, Alexandra Nowbar, Lars Sorensen, Susan Phillip, Dai-Yin Lu, Ioannis Ventoulis, Hongchang Luo, Roselle Abraham and Theodore Abraham from Johns Hopkins HCM Center of Excellence.

HCM can affect people of any age and affects men and women equally. It is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood. Some people who have HCM have no signs or symptoms, and the disease does not affect their lives. Others may have shortness of breath, serious arrhythmias or an inability to exercise. Although HCM is usually inherited, it can also develop over time because of high blood pressure or aging. 

Liu presented a poster based on this research during the American Society of Echocardiography (ASE) 27th Annual Scientific Sessions, June 10-14 in Seattle.

An estimated 44 million people worldwide are currently living with Alzheimer’s disease, the most common form of dementia. About 5.8 million people in the United States live with the disease, where it is the sixth leading cause of death overall. While there is not yet a cure for Alzheimer’s, researchers are working to find treatment options to delay its onset and prevent it from developing.

Fig 1. A sample scoring on CT images of a 63-year-old woman from mortality group demonstrated a total score of 63. It was calculated as: for upper zone (A), 3 (consolidation) × 3 (50–75% distribution) × 2 (both right and left lungs) + 2 (ground glass opacity) ×1 (< 25% distribution) × 2 (both right and left lungs); for middle zone (B), 3 (consolidation) × 2 (25–50% distribution) × 2 (both right and left lungs) + 2 (ground glass opacity) × 2 (25–50% distribution) × 2 (both right and left lungs); for lower zone (C), 3 (consolidation) × (2 (25–50% distribution of the right lung) + 3 (50–75% distribution of the left lung)) + 2 (ground glass opacity) × (2 (25–50% distribution of the right lung) + 1 (< 25% distribution of the left lung)) Yuan et al, 2020 (CC BY 4.0)

Schematic depiction of the automated process for assessing fat, muscle, liver, aortic calcification, and bone from original abdominal CT scan data

Figure 1: Depiction of the fully automated CT biomarkers tools used in this study. (A) Schematic depiction of the automated process for assessing fat, muscle, liver, aortic calcification, and bone from original abdominal CT scan data. (B) Case example in an asymptomatic 52-year-old man undergoing CT for colorectal cancer screening. At the time of CT screening, he had a body-mass index of 27·3 and Framingham risk score of 5% (low risk). However, several CT-based metabolic markers were indicative of underlying disease. Multivariate Cox model prediction based on these three CT-based results put the risk of cardiovascular event at 19% within 2 years, at 40% within 5 years, and at 67% within 10 years, and the risk of death at 4% within 2 years, 11% within 5 years, and 27% within 10 years. At longitudinal clinical follow-up, the patient suffered an acute myocardial infarction 3 years after this initial CT and died 12 years after CT at the age of 64 years. (C) Contrast-enhanced CT performed 7 months before death for minor trauma was interpreted as negative but does show significant progression of vascular calcification, visceral fat, and hepatic steatosis.
