HCM

[JSJS]

Here are the results from my recent Echo, I'm a 37 year old man with history of PAC's & Hypothyroidism. Everything loooks good but I see I'm a 10th of cm over normal on the IVS and Posterior Wall Thickness. Is this anything to be concerned about? All I read about now is HCM and how it goes undiagnosed.
-
Aortic Root Dimension (2.0 - 3.7cm)     3.1
Aortic Valve opening (1.5 - 2.6cm)        1.6
IVS Thickness (0.7 - 1.1cm)                 1.2
Left Atrial Dimension (1.9 - 4.0cm)        3.0
LV Dimension, Diastolic (3.8 - 5.6cm)   4.4
Posterior Wall Thickness (0.7 - 1.1cm)  1.2
LV Dimension, Systolic (2.2 - 4.0cm)    3.0
Ejection Fraction (53 - 77%)                 60%
Pericardial Effusion                              No

Thanks for the response. I have 4 brothers and 1 sister and I don't recall anyone having HCM nor my parents. I do get the symptoms but they are very far in between and i think they relate to my PAC's.

HCM is most often autosomal dominant (genetic, non-sex chromosome).  These numbers look fine.  Any mention of HCM in your family?  If you had it there would be 50/50 chance that each sibling or your kids would have it.  Ultrasound and EKG can help in the diagnosis.  MRI is the best.  Although often asymptomatic, symptoms may include chest pain, dizziness, palpitations, fainting.  Do you experience any of this?
