Marathon runners pre marathon check up: We are seeing increasing cases of marathoners collapsing during the run. Many of them are suffering from heart disease and blockages and are unaware of the same. Hence I recommend that every participant in marathon run must undergo the following tests: ECG 2D ECHO Stress test Sugar test, lipid profile and serum. creatinine X ray chest. CT coronary angiography in high risk patients PFT for select patients. These will pick up those with heart / respiratory problems and then we can suggest remedial measures for optimization before the marathon. This will help prevent untimely deaths during marathon run. For more guidance on pre marathon check ups and remedy you can seek our medical advice on 8657295284. Dr Hardik Thakker, MD Med, ECFMG ( USA).
