The progress of interrelationship between chronic obstructive pulmonary disease and sudden cardiac death / 天津医药

ABSTRACT

Both chronic obstructive pulmonary disease (COPD) and sudden cardiac death (SCD) are major health burdens.In conclusion,cumulating evidence associates COPD with an increased risk of SCD.First,it is found that asystole and pulseless electric activity(PEA)are more common than ventricular tachycardia/ventricular fibrillation(VT/VF)in deaths associated with COPD in studying interrelationship between COPD and ventricul ararrhythmias and cardiac arrest. The underlying mechanism explaining this association requires further investigation.Second,it is found that COPD is associated with a prolonged and shortened QT interval in studying the role of ECG markers between SCD and COPD.Finally,studies of the potential impact of respiratory treatment on the occurrence of SCD showed conflicting results.Accurate prediction of SCD in the general population is still a challenge. The risk assessment of SCD might be guided by studying the link between COPD and SCD.
