Name the disorder that fits each description.
- A man feels a severe pain in the chest when he climbs stairs, and it goes away with rest. The heart muscle has too little oxygen at that moment.
- The wall of the coronary arteries has thick deposits of calcium, fat and cholesterol.
- A woman is breathless, and her lungs are congested with fluid, because her heart is not pumping well enough.
- A patient has a pressure of mm Hg at three checks.
- The heart stops beating. Is this the same as heart failure?
Need a reminder? The key ideaShow
Normal blood pressure is mm Hg. A reading of mm Hg or higher is hypertension. The pulse pressure is the systolic pressure minus the diastolic pressure. In coronary artery disease, deposits narrow the coronary arteries. Angina is a chest pain from too little oxygen in the heart muscle. Heart failure is not cardiac arrest and not a heart attack.
The worked solution
Have you tried it?
Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, go through the solution one step at a time, and check each step against your own.
Step 1. (a) Angina pectoris.
Step 2. (b) Coronary artery disease, also called atherosclerosis.
Step 3. (c) Heart failure, also called congestive heart failure.
Step 4. (d) Hypertension. The pressure is above .
Step 5. (e) No. This is cardiac arrest. In heart failure, the heart still beats but does not pump enough.
Answer: (a) angina; (b) CAD; (c) heart failure; (d) hypertension; (e) cardiac arrest, not heart failure.
