Evidence in support of the spasm of resistance vessel concept of ischemic heart disease: an update in 1993

The goal of this communication is to provide more evidence for the ischemic heart disease (IHD) component of the spasm of resistance vessel (S-RV) concept of IHD and other ischemic diseases. The S-RV concept of IHD is considered to be an alternate paradigm which challenges the accepted understanding of this disorder. The theory asserts that primary S-RV directly induces symptoms in IHD, and this position is in opposition to the accepted view that symptoms are induced directly by primary occlusions of epicardial arteries by coronary artery disease, spasm, and thromboses. The theory, if valid, should be useful in reducing the impact of IHD, as it generally is accepted that the correct appreciation of basic pathophysiological mechanisms helps ensure the most appropriate prevention and treatment of disease.
