Clinical characteristics of cardiomyopathies complicated with ventricular thrombosis

2019 
Objective: To summarize the clinical characteristics of cardiomyopathy complicated with ventricular thrombosis. Methods: The clinical data of inpatients suffered from cardiomyopathy complicated with ventricular thrombosis in Fuwai Hospital between January 2015 and May 2019 were analyzed retrospectively. Results: A total of 125 cases were reviewed, and 24.8% were female. Dilated cardiomyopathy was the most common disease (62.4%), followed by arrhythmogenic right ventricular cardiomyopathy (ARVC) (13.6%) and hypertrophic cardiomyopathy (11.2%). There were 74.4% thrombosis in left ventricle, 12.8% in right ventricle and 12.8% in biventricle. The proportions of right ventricle thrombosis were higher in ARVC than in other cardiomyopathies (52.9% vs 6.5%, P<0.01). The majority suffered from cardiac function New York Heart Association (NYHA) Class (45.6%) and class (39.2%). The ratio of NYHA Class was higher in female patients than in male ones (25.8% vs 10.6%, P<0.05). In lab detection, positive results of D-Dimer and N terminal-pro B type natriuretic peptide (NT-proBNP) accounted for 72.8% and 97.6%, respectively. There were 2.5% patients died in the hospital or discharged because of the worsening of illness, the chances were higher in female than male patients (9.7% vs 0, P<0.01). Among these patients, one succumbed to massive ischemic stroke caused by ventricular thrombus detachment under standard anticoagulation therapy. Conclusions: Dilated cardiomyopathy is the most common cardiomyopathy complicated with ventricular thrombosis. The most common location of thrombosis is left ventricle. Right ventricle thrombosis is more common in ARVC. The majority suffer from moderate or severe cardiac dysfunction. Higer proportion of female patients suffer from anemia, severe condition and poor prognosis.
