Given this paragraph about heart, for how many deaths (in %) as of 2008 do cardiovascular diseases account for?

Cardiovascular diseases are the most common cause of death globally as of 2008, accounting for 30% of deaths.[11][12] Of these more than three-quarters are a result of coronary artery disease and stroke.[11] Risk factors include: smoking, being overweight, little exercise, high cholesterol, high blood pressure, and poorly controlled diabetes, among others.[13] Cardiovascular diseases do not frequently have symptoms but may cause chest pain or shortness of breath. Diagnosis of heart disease is often done by the taking of a medical history, listening to the heart-sounds with a stethoscope, ECG, echocardiogram, and ultrasound.[3] Specialists who focus on diseases of the heart are called cardiologists, although many specialties of medicine may be involved in treatment.[12]
