Possible Clinical Benefits of Cardio-Ankle Vascular Index Measurement in Urological Diseases.

Many factors are considered to affect vascular physiology. It is known that one of the reasons for many diseases is a pathology at the microvascular level. Therefore, the relationship between endothelial dysfunction and many diseases is currently being investigated. The clinical evaluations of arterial stiffness have made it possible to perform necessary risk assessment regarding cardiovascular diseases. In this way, protective measures can be taken against microvascular pathologies in many organs. In this paper, we present a review of studies investigating the relationship between urological conditions and the cardio-ankle vascular index (CAVI), a marker of arterial stiffness. As with erectile dysfunction, some studies have shown that conditions such as lower urinary tract symptoms, overactive bladder, and chronic kidney disease are also associated with an elevated CAVI. The association of erectile dysfunction and chronic kidney disease with vascular pathologies has been clearly demonstrated. In addition, lower urinary tract symptoms may be the first sign of silent vascular dysfunction. Assessing arterial stiffness with CAVI can help prevent future cardiovascular events in these patients.

Assessment of subclinical left ventricular dysfunction with speckle-tracking echocardiography in hyperthyroid and euthyroid Graves' disease and its correlation with serum TIMP-1.

BACKGROUND: Graves' disease has a multitude of effects on the cardiovascular system. In the detection of subclinical left ventricular dysfunction, speckle-tracking echocardiography is more useful than conventional echocardiography. The aim of the present study was to compare the longitudinal global strain values and venous blood concentration of (tissue inhibitor of metalloproteinase-1) TIMP-1, a regulator of the extracellular matrix, among hyperthyroid patients with Graves' disease, euthyroid patients with Graves' disease and healthy control subjects. MATERIALS AND METHODS: The study enrolled 40 hyperthyroid patients with newly diagnosed Graves' disease, 40 patients with Graves' disease who were euthyroid for at least 6 months and 40 control subjects with normal thyroid function. Participants underwent conventional echocardiography and speckle-tracking echocardiography to obtain segmental and global longitudinal strain values. In addition, the serum TIMP-1 value was assessed in the venous blood samples of the participants. RESULTS: The hyperthyroid Graves' patients showed greater serum TIMP-1 levels versus the control group and the euthyroid Graves' group. Compared to the control group, the TIMP-1 level was also significantly higher in the euthyroid Graves' group. Lower GLS (global longitudinal strain) average and GLS2C, GLS3C, GLS4C values were observed in both the hyperthyroid and euthyroid Graves' patients compared to the control group. The euthyroid Graves' patients and hyperthyroid Graves' patients had similar GLS values. The serum TIMP-1 level was negatively correlated with global strain values. CONCLUSION: Graves' disease coexists with impaired segmental and global longitudinal strain and increased TIMP-1 levels. This coexistence seems to be independent of serum thyroid hormone levels.
