Cardiology is about the heart and blood vessels: blood pressure, cholesterol, irregular heartbeat, heart attack warning signs and safe exercise. We explain what your readings and lab numbers mean and which symptoms should never be ignored. The content is for reference and does not replace a doctor's examination.
The two numbers on a blood pressure monitor show the work of the heart as a pump and the resistance of the blood vessels. We break down the ranges, risk factors, and why hypertension causes no pain for years.
Heart attack: classic and subtle symptoms, stages of infarction, and why you shouldn't drive — an analysis for those who train and want to know the numbers.
Bulging veins in the legs are a matter of valve mechanics, not just aesthetics. We break down risk factors, symptoms, duplex ultrasound, and warning signs that shouldn't wait.
LDL, HDL, triglycerides, and total cholesterol: what each test value means and when a result needs a doctor's attention.
Does your heart "skip a beat" during exercise or after coffee? We explain which palpitations are normal and which require an ECG and a visit to a cardiologist.
150 minutes of moderate movement per week is the WHO benchmark for adults. What this gives the heart, how to tell intensity apart, and who needs to talk to a doctor before starting.
