Stable angina
Explanation:
Stable angina is the most common type of angina and therefore, is called typical angina pectoris characterized by a burning heavy and squeezing feeling in the chest (substernal , shoulder ). It is caused by the reduction of coronary perfusion due to a fixed obstruction produced bt coronary atherosclerosis.
The heart becomes vulnerable to ischemia whenever there is increased demand, such as that produced by physical activity ,emotional excitement , or any other cause of increased cardiac workload.
Typical angina pectoris is promptly relieved by rest or nitroglycerin.
As in the above mentioned scenario, Steve hill feels substernal pain after walking from the car thus increasing work load on heart and this pain relieves with rest, this is a characteristic finding of stable angina.
