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.
To Joe C: No, an olive is not a vegetable, it's a fruit. Olive oil is not for baking or cooking at temperatures higher than 250 degrees F because it starts burning and turns into a carcinogen. Butter will give it a very rich flavour, may be too rich for the type of cake your making... not sure.
