Low levels (less than 40 mg/dL) of HDL (good) cholesterol also may increase stroke risk.

Recent studies show that high levels of LDL (bad) cholesterol (greater than 100 mg/dL) and triglycerides (blood fats, 150 mg/dL or higher) increase the risk of stroke in people with previous coronary heart disease, ischemic stroke or TIAs. High blood cholesterol: A high level of total cholesterol in the blood (240 mg/dL or higher) is a major risk factor for heart disease, which raises your risk of stroke.Diabetes, especially when untreated, puts you at greater risk of stroke and has many other serious health implications.

Carotid or other artery disease: The carotid arteries in your neck supply blood to your brain.Controlling your blood pressure is crucial to stroke prevention. That is why it is important to have your blood pressure checked regularly. It usually has no specific symptoms and no early warning signs. High blood pressure: Blood pressure of 140/90 mm Hg or higher is the most important risk factor for stroke.There is recent evidence that long-term secondhand smoke exposure may increase your risk of stroke. Your risk may be increased further if you use some forms of oral contraceptives and are a smoker.
