This inflammation can be caused by an infection or happen after heart attack or heart surgery. Pain from myocarditis or pericarditis is usually is sharp and in the center of the chest.

This idea that it's not a good idea to cook over high heat with olive oil is fairly common. For a lot of people, the concern is one of health, specifically that olive oil, with its relatively low smoke point of 325 to 375Â°F (165 to 190Â°C), degrades more than other oils when exposed to high heat.
The more refined your olive oil, the higher the smoke point. If you are using refined olive oil, such as pure olive oil or light olive oil, it can be as high as 465F or 240C. You can see here where the range specified in the article of 200-250 degrees came from. PLEASE PUBLISH A CLARIFICATION, ERRATUM OR ADDENDUM.
