Abstract :

BACKGROUND & OBJECTIVES: LBBB is often associated with underlying structural heart disease such as IHD, HTN, and idiopathic DCM. This study is an attempt to study clinical and echocardiography profile of LBBB to find various causes, severity and correlation between them.

METHODS: 50 patients who are admitted or attended OPD who has clinical features of heart disease are screened by ECG and diagnosed LBBB, are studied further. Every patients is evaluated with history, clinical examination, 2d ECHO. The results are assessed in terms of causes and severity assessed by 2d echo and their correlation.

RESULTS: LBBB is common in 7^thdecade & male gender. Risk factors in decreasing order are IHD, HTN, Diabetes, smoking, tobacco, and alcohol. In patients with LBBB most patients have higher grade of angina (grade 3) & NYHA class 2– class 3 failure. ECHO finding in decreasing order are Mitral Regurgitation, reduced LV compliance, septal hypokinesia, concentric LVH.LBBB is strongly associated with LV dysfunction. In our study most patients have moderate to severe LV dysfunction & increased LVID d/s.

CONCLUSION: From this study we conclude that LBBB is common in old age & male gender. Modifiable risk factors like IHD, HTN, diabetes, smoking, tobacco and alcohol are associated with LBBB. Echocardiography is useful predictor to evaluate LV dysfunction. By Echocardiographically detected EF%, which shows LV function, clinically correlates with angina & dyspnoea. In patients with LBBB, higher grade of angina and/or NYHA class failure have lower EF and more LVdysfunction.
