Hi Oliver,
Generally, I do not recommend alcohol as a method to treat heart conditions. If you have high triglycerides, alcohol is not beneficial. However, if your HDL is low a moderate intake of alcohol (specifically red wine) may help increase levels.
I recommend you read these two posts and the info specific to alcohol:

Taking steps to improve cholesterol levels and reduce arterial inflammation will reduce angina; however, the burning sensation you are experiencing may be heartburn.

Discuss your symptoms with your MD to determine the best treatment option.
All the best,
