Antihypertensive Drugs and Risk of Bone Fractures.

Antihypertensive drugs are among the most documented regimens worldwide with an overall survival and cardioprotective benefit. However, there is evidence that they cause symptoms of orthostatic hypotension (i.e., dizziness and syncope) placing patients at risk for falls and fall-related injuries such as bone fractures. Moreover, it seems that they might impact bone metabolism and architecture impairing bone health. The aim of this review was to summarize the accumulative literature exploring any potential association between several antihypertensive medications including diuretics, renin-angiotensin-aldosterone system inhibitors, beta-blockers and calcium channel blockers and the risk of fractures.

The impact of financial crisis on coronary artery disease burden in Greece.

BACKGROUND: Economic crisis poses an immense threat to public health worldwide and has been linked to cardiovascular morbidity and mortality. Greece is facing a distinctive recession over the recent years. However, the exact impact on coronary artery disease (CAD) burden has not been adequately addressed. METHODS: Demographic, clinical, and angiographic data of 3895 hospitalized patients were retrospectively studied. Patients were classified into two groups: those before crisis (2006-2007, n = 1228) and those during crisis (2011-2015, n = 2667). RESULTS: All data before and during crisis were compared. During crisis, patients presented with less acute coronary syndrome (ACS - 45.5% vs. 39.9%, p < 0.001). Subsequently, there were more patients without CAD (23.7% vs. 35.1%, p < 0.001) or one-vessel disease (20.5% vs. 23%, p < 0.001). The prevalence of traditional risk factors decreased significantly or remained stable except obesity (26.3% vs. 31.4%, p = 0.002). A significant increase in the examined females (23.6% vs. 26.7%, p = 0.04) was also observed. CONCLUSIONS: The burden of CAD in Greece was partially affected during the financial crisis. Even though the incidence of ACS was decreased, more women and more patients with no- or single-vessel disease were referred for cardiac catheterization. In addition, the prevalence of traditional risk factors for CAD did not increase except obesity confirming the "obesity paradox." It seems that the impact of traditional risk factors for CAD is not an immediate process and is somewhat related to living conditions or other exogenous and social factors.

Aortic dissection and third-degree atrioventricular block in a patient with a hypertensive crisis.

A 55-year-old man with a history of uncontrolled hypertension was admitted because of an episode of severely elevated blood pressure. An electrocardiogram revealed complete atrioventricular block while imaging showed a dissecting aneurysm of the descending thoracic and abdominal aorta, type B according to the Stanford classification. Laboratory tests revealed significant increases in serum C-reactive protein. Coronary arteriography was performed and was negative for coronary artery disease. A VDD pacemaker was placed, and a combination of 4 antihypertensive agents was used as treatment. Type B aortic dissection may present with a wide range of manifestations. The authors suggest that measurement of C-reactive protein may be used in hypertensive patients to help reflect vascular injury and its degree, progression, and prognosis. Disorders of intraventricular conductivity are rarely seen in both types of dissection of the aorta (type A, B). Atrioventricular conductivity disorders that result in complete atrioventricular block have been reported only in patients with type A dissection (before the bifurcation of the subclavian artery). In this particular case, however, the authors diagnosed an atrioventricular conductivity disorder causing atrioventricular block in a patient with type B dissection. Consequently, the authors speculate that myocardial fibrosis, as a result of long-standing hypertension, could be the main pathogenetic mechanism leading to the development of such phenomena, resulting from a potential expanding of the fibrotic process to the atrioventricular conduction system.

Automatic rupture of unused intraport catheter. Case report.

Totally Implantable Central Venous Access Devices (Intraports) are commonly used in cancer patients to administer chemotherapy or parenteral nutrition. These devices are placed by Seldinger technique. We report an unusual case of intraport catheter rupture before the use of the device. The ruptured part of the catheter migrated into the left pulmonary vein via right ventricle. The ruptured part was removed by means of interventional radiology before causing any problems to the patient. All the reported ruptures of port catheters refer to port devices that had been used to administer chemotherapy, fluids, or parenteral nutrition. The unique feature of this case is that the catheter had not been used at all. It is of great interest also the removal of the broken part from the pulmonary vein.
