Insights
In acute ST-elevation myocardial infarction (STEMI) patients, admission serum potassium levels did not predict in-hospital mortality. Advanced age, however, was significantly associated with a higher risk of death.
Area of Science:
- Cardiology
- Internal Medicine
- Clinical Research
Background:
- Potassium levels (hypokalemia and hyperkalemia) significantly impact cardiovascular patient mortality.
- Understanding the role of serum potassium in acute ST-elevation myocardial infarction (STEMI) is crucial for patient outcomes.
Purpose of the Study:
- To investigate the correlation between admission serum potassium levels and in-hospital mortality in STEMI patients.
- To identify predictors of short-term mortality in STEMI patients.
Main Methods:
- A study involving 225 STEMI patients treated with streptokinase at Ayub Teaching Hospital, Abbottabad.
- Serum potassium levels were measured at admission and correlated with in-hospital survival within 72 hours.
Main Results:
- The mean admission serum potassium level was 4.2 mmol/dL, with 74.2% of patients discharged alive.
- While older age was linked to increased mortality risk, serum potassium levels, gender, systolic blood pressure, and heart rate showed no significant association with outcomes.
- Logistic regression confirmed age as a significant predictor of mortality.
Conclusions:
- Admission serum potassium levels did not demonstrate significant predictive value for mortality in STEMI patients.
- Advanced age emerged as a significant factor influencing mortality in this patient cohort.
- Further research is recommended to understand the complex factors affecting STEMI patient mortality and improve management.
Background:
Potassium levels play a significant role in cardiovascular patients, with hypokalemia and hyperkalemia having profound effects on the mortality rate. The aim of this study was to investigate the correlation of admission serum potassium levels and in-hospital mortality in patients suffering from acute ST-elevation myocardial infarction (STEMI).
Methods:
The study was conducted in the Department of Cardiology, Ayub Teaching Hospital Abbottabad, and involved 225 patients with STEMI who underwent thrombolysis with streptokinase. The serum potassium levels of patients were recorded at the time of admission, and its correlation was observed with the short-term outcomes, i.e., discharge to home versus those who did not survive during the hospital stay of 72 hrs.
Results:
The mean level of serum potassium at admission was 4.2 mmol/dL and 74.2% patients were discharged alive. T test indicated that a higher risk of death was associated with old age. No significant association between gender, serum potassium levels, systolic blood pressure, heart rate, and outcomes was seen. Logistic regression analysis further showed that age had a significant association with the outcome of death.
Conclusions:
In our study, age had a significant impact on predicting the mortality of patients with STEMI and whereas the serum potassium levels at the time of admission did not exhibit any significant predictive value. Further research is needed to elucidate the complex interplay of various factors in predicting mortality, to improve the management practices of AMI.

Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
