Relationship Between Left Atrium Volume Index And Major Cardiovascular Events During Nursing In Chronic Heart Failure Patients At Adam Malik Hajj Hospital Medan
Relationship between Left Atrium Volume Index and Major Cardiovascular Events During Nursing in Chronic Heart Failure Patients at Adam Malik Hajj Hospital Medan
Introduction
Chronic heart failure (CHF) is a complex and multifactorial disease that affects millions of people worldwide. It is characterized by the heart's inability to pump enough blood to meet the body's needs, leading to a range of symptoms and complications. One of the key factors in the assessment and management of CHF is the size of the left atrium, which plays a crucial role in the heart's pumping function. In recent years, the measurement of left atrial volume index (IVAK) has become a widely accepted method for assessing the size of the left atrium. However, the prognostic value of IVAK in the context of CHF is still not well understood.
Background
The size of the left atrium in the assessment of heart failure can now be measured more accurately using the volume of the left atrium than the dimensions of the left atrium that uses the M-Mode method. Considering the left atrium is an asymmetric cavity, volume measurement is considered more representative than the measurement of area or linear dimensions. The left atrial volume index (IVAK) plays an important role in impressing risk for heart failure patients. However, the prognostic value of IVAK in the context of heart failure is still rarely examined. This study aims to identify whether there is a relationship between IVAK and major cardiovascular events (KKVM) during the treatment of heart failure patients at the Adam Malik Hajj Hospital in Medan.
Research Methods
This study is a prospective cohort study involving patients with chronic heart failure treated at Adam Malik Hajj Hospital Medan between September 2017 and December 2017. Every research subject underwent echocardiographic examination to assess IVAK and other echocardiographic parameters. Patients will be monitored during the treatment period at the hospital to assess the KKVM incidence. After that, the analysis was carried out to identify the relationship between IVAK and KKVM.
Research Result
From the results of the study, the group of patients with chronic heart failure with ivak ≥ 34 ml/m² showed the incidence of KKVM that was higher than the group with IVAK <34 ml/m², which was 17 people (85%) compared to 3 people (15%) with a P value = 0,000. In addition, groups with IVAK ≥ 34 ml/m² also have a higher incidence of mortality, with 8 people (100%) compared to 0 people (0%) in groups with IVAK <34 ml/m². The specified cutoff value is ≥ 34.5 ml/m², which can predict KKVM events with 70% sensitivity and 65.5% specificity. Multivariat analysis revealed that the only independent factor that could predict the occurrence of KKVM during the treatment period is ivak ≥ 34 ml/m² [or 7.158 (1,824-28,085), p = 0.005].
Discussion
The results of this study suggest that there is a significant relationship between IVAK and major cardiovascular events (KKVM) in patients with chronic heart failure. Patients with high IVAK (≥ 34 ml/m²) had a higher incidence of KKVM and mortality compared to those with low IVAK (<34 ml/m²). The specified cutoff value of ≥ 34.5 ml/m² can predict KKVM events with 70% sensitivity and 65.5% specificity. These findings are consistent with previous studies that have shown that IVAK is an independent predictor of adverse outcomes in patients with heart failure.
Conclusion
Based on the analysis of the results of this study, it can be concluded that IVAK is an independent predictor of the KKVM incidence, with an odds ratio (OR) of 7,158. This shows that patients with high IVAK have a greater risk of experiencing major cardiovascular events, which emphasizes the importance of measuring IVAK as a tool in handling and prognostic heart failure. This is important for doctors and medical personnel to consider IVAK in the management strategy of heart failure, in order to increase patient care results. With this understanding, it is expected that early intervention can be carried out for patients with high risk, so as to reduce the incidence of KKVM and related mortality.
Implication
The findings of this study have several implications for the management of chronic heart failure. Firstly, the measurement of IVAK should be considered as a routine part of the assessment and management of heart failure patients. Secondly, patients with high IVAK should be considered at high risk of experiencing major cardiovascular events and should be closely monitored and managed accordingly. Finally, early intervention should be carried out for patients with high risk, such as those with high IVAK, to reduce the incidence of KKVM and related mortality.
Limitation
This study has several limitations. Firstly, the sample size was relatively small, which may limit the generalizability of the findings. Secondly, the study was conducted in a single hospital, which may limit the external validity of the findings. Finally, the study did not control for other potential confounding variables, such as age, sex, and comorbidities, which may have affected the results.
Future Research
Future research should aim to replicate the findings of this study in larger and more diverse populations. Additionally, studies should investigate the relationship between IVAK and other outcomes, such as hospitalization and quality of life. Furthermore, studies should explore the potential mechanisms underlying the relationship between IVAK and major cardiovascular events, such as the role of inflammation and oxidative stress.
