Small sense of pain sometimes in heart.

Hi, I am 29 years old. I am facing sometime problem like a very very light pain in my heart. I am not under any medication and also non diabetic. I got myself tested last month with complete blood profile I have a stage one fatty liver which was shown in ultrasound and after this I got myself tested with liver profile test so, I have slightly increased level of LDL just above normal range. Physician just suggested to avoid alcohol and junk food and follow some good food routine with some exercise. But I have a fear of this pain so every now and then I am getting my blood pressure checked . So, the results were sometime 160/110 and sometime just normal like 120/80 and sometime 150/90. So I don't know exactly what is the problem. I guess my blood pressure is rising because of cholesterol levels So, can someone suggest what should I be doing. I don't want to end up taking medicine for my blood pressure and fatty liver at later stages. Also let me know if this is warning sign for somthng
