The gold standard for determining arterial blood gas levels is actually measuring arterial blood samples with a blood gas machine to get information on the arterial oxygen partial pressure (PaO2), pH and carbon dioxide partial pressure (PaCO2).
Hypertrophic cardiomyopathy (HCM) is a primary myocardial disease that primarily affects left ventricular (LV) myocardium and is characterized by mild to severe thickening (concentric hypertrophy) of the LV wall (septum and/or free wall) and papillary muscles.
In humans, the familial nature of HCM was first reported in 1958. It has been demonstrated that over 70% of human cases of HCM are inherited in an autosomal dominant pattern, with most other cases being sporadic (although often still genetic in origin).
Dilated cardiomyopathy (DCM) is a cardiac disease due to an inherent abnormality in the myocardium that results in a decrease in myocardial contractility (i.e., myocardial failure) and is not secondary to another primary disease.
Studies have been performed in humans to determine if early administration of ACE inhibitors to human patients with ischemic dilated cardiomyopathy decreases the progression of myocardial failure and so reduces mortality.
