Changing axis deviation, paroxysmal atrial fibrillation and elevation of prostate-specific antigen during acute
Insights
This study reports a rare case of changing axis deviation and atrial fibrillation during acute myocardial infarction. It also observed elevated prostate-specific antigen (PSA) levels, confirming previous findings.
Area of Science:
- Cardiology
- Oncology
Background:
- Left bundle branch block with changing axis deviation during acute myocardial infarction is rarely reported.
- Prostate-specific antigen (PSA) is a key biomarker for prostate cancer detection.
- Previous studies noted transient PSA increases after exercise and potential fluctuations during acute myocardial infarction.
Observation:
- A rare case of an 88-year-old man experiencing changing axis deviation and atrial fibrillation during acute myocardial infarction is presented.
- Serum PSA concentration was observed to elevate during the acute myocardial infarction event.
- This case aligns with and extends previous observations on PSA behavior during myocardial infarction.
Findings:
- The co-occurrence of changing axis deviation, atrial fibrillation, and elevated PSA during acute myocardial infarction is confirmed.
- The findings support the potential utility of monitoring PSA in the context of acute myocardial infarction, despite previous reports of variable results.
Implications:
- This case highlights the complex interplay of cardiac events and biomarker changes during acute myocardial infarction.
- Further research may elucidate the precise mechanisms behind PSA elevation and its prognostic significance in cardiac patients.
Abstract:
It has been rarely reported left bundle branch block with changing axis deviation also during acute myocardial infarction. It has also been rarely reported changing axis deviation with changing bundle branch block during acute myocardial infarction. Prostate-specific antigen (PSA) is an established tool in detecting prostate cancer. Immediately after 15 min of exercise on a bicycle ergometer, serum PSA concentrations increased by as much as threefold. Apparently spurious result has been reported in a work about mean serum PSA concentration during acute myocardial infarction with mean serum PSA concentration significantly lower on day 2 than either day 1 or day 3 and it has been reported that these preliminary results could reflect several factors, such as antiinfarctual treatment, reduced physical activity or an acute-phase response. We present a case of changing axis deviation with onset of atrial fibrillation and elevation of serum PSA concentration in an 88-year-old Italian man during acute myocardial infarction. Our report confirms previous findings and extends the evaluation of PSA during acute myocardial infarction.
