Cardiopathy and osteoporosis: the epidemiology in a region of Italy.

Cardiopathies and osteoporosis are inter-related due to pathogenetic, hormonal, genetic features as well as an increased risk of fragility. An important feature is attributed to the process of atherosclerosis, which is responsible for an osteopenia effect and degeneration of vascular walls. To date the study populations have been limited. To verify the incidence of cardio-vascular disease in a larger osteoporotic population, we designed a retrospective clinical study analyzing the “Hospital Discharge Data” (HDD) in Apulia between 2006 and 2010. All patients over 55 years with a hospitalization for a fragility fracture and/or drugs prescription for osteoporosis were crossed with the diagnosis and/or drugs prescription for cardiovascular disease. We observed that between 2006 and 2010, in Apulia, 177,639 patients were hospitalized and diagnosed as having fragility fractures, 66.3% had a diagnosis of cardiopathy, with a higher prevalence in males and in patients over 80 years. The incidence of fractures were as follows: femur (51.9%), spine (20.2%), humerus (10.6%), forearm (9%), tibial pilon (7.2%) and tarsus and metatarsus (1.1%). Cerebrovascular diseases were the most frequent, followed by arrhythmias, heart failure and cardiomyopathies. In these patients, the most prescribed drugs were anti-coagulants, ACE inhibitors and diuretics. In patients affected by cerebral circulation disorder there is a greater propensity to fall and thus have a fragility fracture, particularly of the femur. The vertebral fracture, misdiagnosed in 60-70% of patients, may compromise the cardio-respiratory function of these patients. We verified a higher incidence of fragility fractures in patients who were prescribed certain categories of drugs for the treatment of cardio-vascular disease. This hypothesis is not supported by the literature, where contradictory results on the potential effects of these drugs on bone have been published. The high incidence of heart disease found in patients with fragility fractures supports the need for specific screening for osteoporosis in the population with cardio-circulatory pathology.
