“…The presence of LBBB with MI is associated with higher in‐hospital and long‐term mortality . When compared with RBBB, patients with new LBBB have a higher 30‐day and 7‐year mortality . In‐hospital mortality is also higher in patients with new BBB compared to those with old BBB .…”

“…New bundle branch block (BBB) was determined in 28% of these patients, and the remaining percentage represented either existing or unknown onset BBB. It can therefore be deduced that the development of new LBBB in patients with inferior MI was <1% …”

“…In‐hospital mortality is also higher in patients with new BBB compared to those with old BBB . The association between high mortality and MI with bundle branch block is thought to be due to large infarctions in RBBB and considerable comorbidities in LBBB . There is increasing data in the thrombolytic era suggesting that although BBB is historically associated with higher mortality, it is not an independent predictor of mortality due to the presence of other strong predictors in this patient population, such as advanced age and impaired ejection fraction …”

Left bundle branch block following inferior myocardial infarction remains uncommon and scarcely reported in the literature. We describe a rare presentation of a 58-year-old male patient who developed left bundle branch block and third degree atrioventricular block after inferior myocardial infarction requiring permanent pacemaker placement. Pathophysiology, impact on mortality, and management options are discussed.

“…Right bundle branch block as well as LBBB have been associated with increased mortality. 33,34 Urena et al have reported that NOP-LBBB is associated with decreased LVEF and poorer functional status at 1-year follow-up. 13 In TAVI patients, lower LVEF is a negative prognostic factor.…”

New-onset persistent left bundle branch block (NOP-LBBB) is one of the most common conduction disturbances after transcatheter aortic valve implantation (TAVI). We hypothesized that NOP-LBBB may have a clinically negative impact after TAVI. To find out, we conducted a systematic literature search of the MEDLINE/PubMed and Embase databases. Observational studies that reported clinical outcomes of NOP-LBBB patients after TAVI were included. The random-effects model was used to combine odds ratios, risk ratios, or hazard ratios (HRs) with 95% confidence intervals. Adjusted HRs were utilized over unadjusted HRs or risk ratios when available. A total of 4049 patients (807 and 3242 patients with and without NOP-LBBB, respectively) were included. Perioperative (in-hospital or 30-day) and midterm all-cause mortality and midterm cardiovascular mortality were comparable between the groups. The NOP-LBBB patients experienced a higher rate of permanent pacemaker implantation (HR: 2.09, 95% confidence interval: 1.12-3.90, P = 0.021, I 2 = 83%) during midterm follow-up. We found that NOP-LBBB after TAVI resulted in higher permanent pacemaker implantation but did not negatively affect the midterm prognosis. Therefore, careful observation during the follow-up is required.

“…As reported in many studies, right bundle branch blocks are more common in elderly patients and patients with anterior myocardial infarctions. In addition, right bundle branch blocks significantly increase the mortality rate (7)(8)(9)(10). A recent study showed that arrhythmias and conduction disorders are more common in people with ACS and impaired renal function, and that this weakened their prognosis (11).…”

Background: Acute coronary syndrome (ACS) is one of the most common heart diseases. Interventricular conduction disorders are complications of acute myocardial infarctions and have different types, such as left and right bundle branch blocks and left anterior and posterior hemiblocks. The prognosis of this disease can affect therapeutic methods, duration of hospitalization, and timely intervention decisions. Therefore, in this study, we evaluated the relationship between interventricular conduction disorders and the prognosis of patients with ACS.Methods: Using the convenience sampling method, this analytical case-control study was conducted on 140 patients with ACS (61 patients in the case group and 79 patients in the control group) who were treated from March to August 2013. The underlying variables of the risk factors for ACS were evaluated, along with prognostic evaluation factors, in two groups: a case group (patients with interventricular conduction disorders) and a control group (patients without interventricular conduction disorders). Data were analyzed with SPSS v. 17 software using the chi-squared test, the analysis of variance test, Student’s t-test, and Fisher’s exact test. Results: The mean age of patients was 64.1 ± 5.8 years in the case group and 62.9 ± 8.8 years in the control group. No significant relationship was observed between ACS risk factors, such as hyperlipidemia, diabetes, hypertension, previous myocardial infarction, and smoking, and the prognosis of patients with ACS. The mean ejection fraction was 39.7 in the case group and 45.1 in the control group, so a significant relationship existed between the two groups (P<0.05). In addition, systolic heart failure was more common in the case group than in the control group.Conclusion: We found that the presence of auscultation (rales sound) and shortness of breath on the first day of hospital admission in the case group was significantly different from the control group (P<0.05). Furthermore, the ejection fraction in the case group was lower than in the control group, and the frequency of mitral regurgitation in the case group was higher than in the control group. These factors can effectively predict the prognosis of patients with ACS. Finally, we found that interventricular conduction disorders weakened the prognosis of patients with ACS.
