# 1 killer in the United States. Heart Disease. < 20 LOW. 20-29 MODERATE. AT RISK?. 30-45 HIGH. > 45 EXTREMELY HIGH. CAROTID ARTERY. RADIAL ARTERY. Medical disorders that affect the heart and blood vessels. Heart, blood, and arteries are parts of the circulatory system.
THE ANATOMY FIRST
Blood pressure is the force of blood against the walls of blood vessels as blood flows through the circulatory system.
Known as the “silent killer”
Risk Factors: obesity, alcohol use, inactivity, smoking, excessive salt intake.
Prevention: no cure; controlled by life style changes- diet, losing excess weight and exercise. Medication.
Arteriosclerosis blood vessels as blood flows through the circulatory system.
A progressive weakening of the heart muscle that reduces its ability to pump effectively
Atherosclerosis- biggest cause
When the heart cannot pump well, results in either poor output- (blood cannot get to the vital organs- or the blood backs up leading to excess fluid)
Medications can be prescribed to prevent episodes, but it is important to watch fluid and salt intake, monitor weight and seek help early.

Heart Transplant- ability to pump effectively replacing damaged heart with a heart from a person who recently died.
Coronary Bypass Surgery- creates detours around obstructed arteries so blood can reach the heart.
Balloon Angioplasty- catheter is inflated in site of blockage to push plaque against artery wall to open a path.
Heart Valve Surgery- valve can be too tight or big, surgery replaces defective valve with an artificial one made of metal or plastic.Surgical Procedures
chest compressions to circulate oxygenated blood
