Heart attack symptoms. For angiogram?

Dear Doctor Every year I do a body check up.. In 2019 November I went to Narayana Hrudyalaya Bangalore...where I did all test ..My ECG ,Echo all came normal... Cholesterol leavel also almost normal.. But last month I repeat cholesterol test . Result came as Total cholesterol-180,Trygliceride-130 HDL-15 Direct LDL-137 Non HDl-165 Now from few days I am feeling discomfort in my arms and  sometime in neck(last few seconds) I am fearing heart attack. Bp is 128/80. Taking bp medicine from last 4years... Kindly suggest me... In 2017 I did Hotler test, Ambulatory test also...both came normal ..In 2019 November ECHO and Ecg which came normal... Is there anything serious?? Should I repeat echo ? Is there any need for angiogram? I am in fear... kindly suggest me
