<s>[INST] I went to ER with chest pains. Results no heart attack. Had echo and stress test next day and the dr said enlarged heart ? I ask what causes that aND he said high BP, but Ive never had:( my BP runs about 117/74 to maybe 120/76.. Any idea about what I should or shouldnt do? [/INST] Hello, I have gone through your query. Thanks for using ChatDoctor.in your information there is some paradoxical information. ECHO can not be normal if heart is enlarged. But sometimes thickened wall of ventricles produce enlarge shadow on X-ray chest, this may be a possibility. Commonest cause of such thickened heart walls is high BP.few normal readings of blood pressure do not rule out hypertension. I suggest you to get Ambulatory BP monitoring RO rule out hypertension in your case.I need to review your ECG, echo to guide you properly best wishes Chat Doctor.  </s>
