Biventricular pacing has been used as an adjunct to standard heart failure therapy in symptomatic patients with left bundle branch block (LBBB). Estimates of the number of patients for whom this treatment is appropriate are unavailable, but are of clinical and socioeconomic importance. LBBB combined with a low (< 0.35) ejection fraction was found in 7,121 consecutive patients referred for elective diagnostic angiography in 1996 through 2000 from a total population of about 125,000 residents. Patients with LBBB (n = 289, 4%) had lower ejection fractions (0.53 +/- 0.23) in comparison with patients without LBBB (P < 0.0001). The ejection fraction was < 0.35 in 558 (8%) patients. LBBB was combined with a low ejection fraction in 96 (1.4%) patients (i.e., 19 patients per year and about 15 patients per year per 100,000 residents). Of these 96 patients, 80 had normal sinus rhythm, 82 had mitral regurgitation (grade > II), 86 were < 75 years of age, and 68 had coronary artery disease. Holter recordings performed in 47 of 96 patients showed nonsustained VT in 28 (60%). LBBB, low ejection fraction, sinus rhythm, and age < 75 years were found in 71 (1%) patients (i.e., 11 patients per year per 100,000 residents). The prevalence of LBBB combined with severely impaired left ventricular ejection function is about 1-2% in patients who undergo cardiac catheterization. The authors estimate that biventricular pacing might be considered as an adjunct to standard heart failure therapy in five to ten patients per year per 100,000 residents in industrial countries. About half of these patients are potential candidates for implantation of cardioverter defibrillators combined with permanent pacing.
