Osteoporosis and atherosclerosis are important public health problems that often coexist, especially in the elderly.

The aim of our study was to evaluate the cardiovascular risk in a population of patients affected by osteoporosis, by measuring the carotid intima-media thickness (IMT) and the Pulse Wave Velocity (PWV), comparing these results with those of a healthy control population. 58 patients with osteoporosis and an equal number of healthy control subjects were enrolled. All subjects underwent a bone densitometric examination using a DXA technique, a vascular evaluation for the measurement of PWV and IMT, and a blood sample for the evaluation of the lipidic and phosphocalcic metabolism.

L’osteoporosi e l’aterosclerosi sono importanti problemi di salute pubblica che spesso coesistono, in particolar modo nella terza età. Sebbene alcuni studi riportino una relazione età dipendente, altri suggeriscono una relazione causale tra osteoporosi ed aterosclerosi. A parte il fatto che le due patologie condividono comuni fattori di rischio, numerosi studi hanno esplorato negli ultimi anni vari “pathways” biologici e molecolari che potrebbero legare le due patologie indipendentemente dall’età. L’obiettivo dello studio era valutare in una popolazione di pazienti affetti da osteoporosi il rischio cardiovascolare, attraverso la misurazione dello spessore medio-intimale carotideo (IMT) e della Pulse Wave Velocity (PWV), confrontando tali risultati con quelli di una popolazione sana di controllo. Sono stati arruolati 58 pazienti con osteoporosi e un pari numero di soggetti sani di controllo. Tutti i soggetti sono stati sottoposti ad esame densitometrico osseo mediante tecnica DXA, valutazione vascolare per la misurazione della PWV e dell’IMT e prelievo per la valutazione dell’assetto lipidico e del metabolismo fosfo-calcico. I pazienti osteoporotici presentavano un incremento significativo della PWV e dell’IMT. Il nostro studio dimostra che, a parità di fattori di rischio, i pazienti affetti da osteoporosi presentano un invecchiamento vascolare più precoce, con un aumento della rigidità arteriosa. Inoltre abbiamo osservato una significativa correlazione inversa tra i valori di BMD femorale e la PWV e ciò contribuisce a sostenere un possibile ruolo causale dell'osteoporosi sull’invecchiamento vascolare.

Abstract
Osteoporosis and atherosclerosis are important public health problems that often coexist, especially in the elderly. Although some studies report an age-dependent relationship, others suggest a causal relationship between osteoporosis and atherosclerosis. Apart from the fact that the two pathologies share common risk factors, in recent years numerous studies have explored various biological and molecular "pathways" that could link the two pathologies, regardless of age. The aim of our study was to evaluate the cardiovascular risk in a population of patients affected by osteoporosis, by measuring the carotid intima-media thickness (IMT) and the Pulse Wave Velocity (PWV), comparing these results with those of a healthy control population. 58 patients with osteoporosis and an equal number of healthy control subjects were enrolled. All subjects underwent a bone densitometric examination using a DXA technique, a vascular evaluation for the measurement of PWV and IMT, and a blood sample for the evaluation of the lipidic and phosphocalcic metabolism. Osteoporotic patients had a significant increase in PWV and IMT. Our study shows that, considering the same risk factors, patients with osteoporosis have an earlier vascular aging, with an increase in arterial stiffness. We also observed a significant inverse correlation between the values of femoral BMD and PWV, and this helps to support a possible causal role of osteoporosis on vascular aging.File | Dimensione | Formato | |
