Kaspar Broch successfully defended his thesis "Dilated cardiomyopathy: diagnostic work-up, pathogenesis, prognosis and treatment" in February 2016.

The studies in his thesis demonstrate an increased survival rate for patients diagnosed with dilated cardiomyopathy. This is a heart muscle disease that causes impaired heart pump function without coronary artery disease, valve disease or high blood pressure. It is thought that many of the cases are due to viral infection or gene defects, but most often the cause remains unclear. Life prospects have previously been reported to be significantly reduced.

Physician and researcher Kaspar Broch followed 102 patients with dilated cardiomyopathy over several years. Despite extensive research into the underlying cause, this was revealed in only a small number of patients. Nevertheless, morbidity was moderate and survival was good with modern heart failure treatment in these patients. The level of a new disease marker called ST2 is elevated in patients with heart failure. In Broch's patient group, ST2 was related to the degree of heart failure, but not to the underlying cause or amount of fibrous tissue in the heart. This suggests that ST2 may not reflect the disease process in the heart, as previously thought. When interperating blood tests, it is important to keep this in mind.

Cholesterol-lowering drugs called statins can have anti-inflammatory properties. One theory has been that the effect of statins is as much due to these properties as the reduction of cholesterol itself. In a study in which 72 patients with dilated cardiomyopathy were randomly assigned to rosuvastatin or narcotic drugs, Broch and co-workers showed that although cholesterol levels dropped significantly in the statin group, neither the degree of heart failure nor the degree of inflammation was attenuated. This result suggests that statins have no intrinsic anti-inflammatory effect and cannot be used to treat heart failure of this type.
