Acute coronary syndrome (ACS) is a common but diagnostically challenging condition in general practice. Its clinical presentation is often atypical or subtle, which can delay recognition. Late diagnosis or inappropriate management may result in poor outcomes and medico-legal consequences. Enhancing diagnostic skills in primary care is essential to ensure timely treatment and patient safety.This report presents case studies of patients diagnosed with ACS in a general practice setting. Point-of-care testing (POCT) for cardiac biomarkers and electrocardiogram (ECG) recordings were performed directly in the outpatient clinic. The diagnostic process, clinical decision-making, and referral to specialized cardiology centers were analyzed. Current best-practice recommendations for ACS management in primary care are summarized. The cases illustrate varied presentations and highlight the role of rapid diagnostics in improving care.These cases show that POCT and ECG are useful tools for general practitioners. The new point is that fast testing can directly improve patient outcomes. Finding problems early in primary care shortens the time from first contact to treatment, and lowers the risk of complications. Using these tests correctly in daily practice can greatly improve patients’ chances of recovery.Timely use of POCT and ECG directly enhances quality of care and patient safety. General practitioners should be trained in rapid cardiovascular diagnostics and interpretation of test results. Future efforts should focus on wider implementation of POCT, structured GP training, and increased awareness of early intervention in suspected ischemic conditions. These measures can improve early diagnosis, reduce treatment delays, and enhance overall clinical outcomes.Early and accurate diagnosis of ACS in primary care remains central to effective pre-hospital management. Integration of POCT and ECG allows GPs to identify high-risk patients, initiate appropriate actions, and ensure timely referral. These practices support well-coordinated regional networks for acute cardiac care and improve patient outcomes. Systematic use of ECG and POCT improves the diagnostic efficiency of general practitioners managing suspected ACS. It shortens the time to treatment and contributes to better patient outcomes within a collaborative healthcare system
