This study aims to determine the effect of multimedia-based education on the management of hypertension on changes in stroke prevention behavior. The method in this study uses a quasi-experimental pre-post and post-test with control group design. The study population was all elderly with hypertension in Cipayung District, East Jakarta. The sampling technique uses purposive sampling. The number of samples in 64 respondents, in the intervention group and the control group. The method of data collection by pre-post and post-test, the data characteristics of respondents, knowledge, attitudes and actions using a questionnaire. While the blood pressure data checks the respondent. The study was conducted in the working area of ​​the Cipayung District Health Center in East Jakarta, the time of the study was from April to November 2019. Interventions that were conducted to respondents were multimedia-based education using Video and Modules. Univariate and bivariate data analysis, using the dependent and independent t-test while multivariate data analysis using the mancova test. The results showed that the average age of respondents was 63 years in the intervention group, while the control group was 62 years. The majority of respondents are female, not working and have low education both in the control and intervention groups. There are significant differences in multimedia-based education on respondents' knowledge, attitudes, actions and blood pressure. There is a significant influence between respondent's age, occupation and systolic blood pressure on stoke prevention behavior. Conclusion: There is a significant difference in multimedia-based education on changing the behavior of respondents for stroke prevention.

Acute Coronary Syndrome (ACS) is one of the clinical manifestations of coronary heart disease that most often causes of death. A sensitive laboratory examination to assess the presence of signs of myocardial infarction such as troponin I is used to diagnose ACS. Electrolyte levels can also be impaired in myocardial infarction. Electrolyte imbalance in the blood can affect the conduction and contractility of the heart, especially sodium and potassium which are needed to produce activation of the heart muscle. The aim of this study was to determine the correlation between troponin I levels and sodium and potassium levels of serum in acute coronary syndrome patients with diabetes mellitus. The research design was used a cross sectional analytical observation with secondary data. This study was used the Spearman correlation test with an alpha value of 0.05. The data were taken from the medical records section of Budhi Asih Hospital. The samples were used 65 data of patients. The results showed that there was a correlation between troponin I levels and sodium with a p value 0.001 (p < 0.05), getting a fairly strong closeness level (r = -0.390) and negative direction. Likewise, the levels of troponin I with potassium showed a p value 0.000 (p < 0.05), getting a fairly strong level of closeness (r = -0.487) and a negative direction. From this study, it can be concluded that there was a relationship between troponin I levels with sodium and potassium with a negative correlation direction which indicates that the higher troponin I levels, so the lower the sodium and potassium levels. Electrolyte examination, especially sodium and potassium, is important to help diagnose acute coronary syndrome in knowing the balance of body fluids so as to prevent death.
