MedicalResearch.com: What is the background for this study?
Response: Cardiovascular disease (CVD) is the leading cause of on-duty death among firefighters (45% of on-duty fatalities) and a major cause of morbidity. It is crucial to note though, that the risk of on-duty CVD events is not evenly distributed among all firefighters, but is highly concentrated among the most susceptible individuals. Given that firefighting is an inherently dangerous occupation and many of its hazards cannot be engineered out of the job, we have concentrated our efforts on understanding what can make an individual firefighter susceptible.
As in the general population, these cardiovascular events are largely due to coronary heart disease (CHD), however, there is an increasing recognition of the role of left ventricular (LV) hypertrophy/cardiomegaly in the risk of sudden cardiac death (SCD) independent of the presence of CHD. Evidence suggests an improved prognostic value, when LV hypertrophy is based on the accurate assessment of LV mass.
LV mass is a strong predictor of CVD events and despite it’s critical prognostic significance, it’s measurement and role in clinical practice has yet to be established.
In this paper we aimed to identify the most important predictors of LV mass after indexing for height among career male firefighters as assessed by both echocardiography and cardiac magnetic resonance.
