Right side dysfunction implications?

[p1954]

Sept 2012 had a stress induced cardiac event (Takotsubo cardiomyopathy per my cardiologist) which damaged my left ventricle.  LVEF about 45% a year ago but don't yet have recent test results .   Also had 2 stents put into my right coronary artery at that time although the RCA was not involved in the event.

Recent echo showed no degradation in LV or LVEF:   45-50% LVEF, mild hypokinesis of some walls but no hypertrophy.   Tricuspid valve Doppler indicates elevated right side pressure of 55 mm.   Mean pulmonary artery pressure of 30 mm.  report says pressures are consistent with moderate pulmonary hypertension and that right side pressure is due to diastolic dysfunction.   Started on Losartan.

Does this mean that my lungs are involved, causing back pressure or that heart failure is causing the pulmonary  
hypertension?    Should I see a pulmonary specialists or is this all heart related within the realm of my cardiologist?

thanks

I just answered your other post.  It wasn't clear to me from that post that the 30mm PA pressure was the mean, not the systolic, so that may be accurate and may be consistent with some pulmonary hypertension.  However given your dysfunction in your left ventricle, often times the elevated right heart pressures are due to elevated left heart pressures which is likely the case here.  A right heart cath would certainly answer that question.  Hope this helps!

thank you.  I will ask for clarification from my cardiologist as on hindsight we did not discuss this last week, and I am disappointed the he did no call me in earlier as the echo was done 8 weeks prior to last week's office visit.  I read "consistent with moderate pulmonary hypertension"  with respect to the 30 mm calculated mean pulmonary artery pressure on the echo report after getting home and became concerned because PH is very serious and this seems to point to a more negative outlook..
