I'm a bit worried because I have diabetes and this morning I felt a slight pain on the left side of my chest. I went to the hospital, and they did an ECG. The report said "Borderline," but it was unconfirmed. The doctor told me it's not a huge problem but that I need to watch my diet and keep tabs on my heart health. I'm a little confused and can't help but worry about what all this means. Could you help me understand? Ive been losing sleep over this.

Salt restricted diet,DASH diet for hypertension...reduced fats ,oils,butter and ghee reduction advised...
