Prevalencia de Bloqueo de Rama Izquierda en pacientes con diagnóstico de Angina Inestable entre los 45 a 65 años que ingresaron en el Hospital Alcívar durante el período 2021 – 2022.

Abstract

Research on the prevalence of left bundle branch block in patients aged 45 to 65 years with unstable angina is important for understanding this cardiac condition and its relationship to coronary artery disease. The results may guide future research and prevention strategies in a global public health context. The aim of this thesis is to associate the presence of Left Bundle Branch Block (LBBB) in patients diagnosed with Acute Coronary Syndrome (ACS) admitted to Hospital Alcívar during the period 2021-2022 and to estimate the prevalence of patients with LBBB and Acute Myocardial Infarction (AMI). We used a quantitative and observational approach, with a cross-sectional design. The information was collected from medical records, with a sample of 34 patients, and the data were analyzed with Excel to evaluate the frequency distribution and percentage of the categorical variables. The results show that 41% of the population examined had ACS, with ST-segment elevation acute myocardial infarction being the most common (44%), followed by non-ST-segment elevation acute myocardial infarction (44%), and only 15% had unstable angina. These findings are consistent with the medical literature and support the typical presentation of these diseases in patients with ACS. This study provides an important basis for future research and prevention strategies for cardiovascular disease, a significant global public health challenge.
