Cardiac stem cells replacing scar tissue.
Very interesting that this did not increase the pumping strength of the heart. Very disappointing. On the other hand, many of the cardiac drugs of today do decrease the irritability of the heart and therefore suppress the strength of myocardial contractility. Many years ago the chief cardiac drug was digitalis, derrived from the foxglove plant. It poisoned the AV node and thereby slowed the heart rate but acted as a tonic on the left ventricle and increased the strength of that chamber. Maybe we need to bring back a few of the older drugs.
