Hello Dr. I am 26 years old and I ate a cannabis cake and 2 hours later, i got a panic attack, i induced vomiting it out.

I was taken to a bearby clinic and my pressure was 150/90mmHg with 150 bpm.

I was given sublingual nifedipine and magnesium sulphate.

I realised my pulse rate remained in the range of 140 - 100 for over 6 hrs but was discharged.

Three months later i did an Ecg and Echo cardiography tha showed left ventricular grade 1 diastolic dysfunction.

Qns.

1. Did nifedipine induce reflex tachycardia and heart ischemia?

2. Does my Ecg show that i had a heart attack?

3. At my age what causes diastolic dysfunction and what is my life expectancy after this diagnosis, is the condition reversible?
