"Four Signs You Should Consider a Heart Checkup Immediately, Warns Cardiologist" — A Comprehensive Explanation of Japan's Health Checkup System and the Situation Overseas

A feeling of chest pressure, shortness of breath with minor activities, extreme fatigue that doesn't go away with rest, and irregular heartbeat (palpitations or arrhythmias) are four symptoms that cardiologists in the UK identify as strong signals for when you should get your heart checked. Chest pain doesn't always manifest as the "intense pain" seen in movies; it can also appear as a pressing or squeezing sensation, or discomfort similar to heartburn. Shortness of breath, difficulty breathing at night, unexplained fatigue, and irregular pulse may indicate underlying conditions such as angina, heart failure, or atrial fibrillation. In cases of suspected emergencies, dial 119 in Japan (or #7119 if unsure), 999 in the UK, or 911 in the US. We compare Japan's "Specific Health Checkups" (ages 40–74) and the Suita Score risk assessment, the UK's NHS Health Check (ages 40–74, every 5 years), and the US USPSTF guidelines for hypertension and dyslipidemia screening. This article summarizes the tests you should undergo based on symptoms, age, and risk, as well as guidelines for seeking medical advice and self-check methods.
