PWA gives estimates of several parameters characterizing the pressure load of central circulation and the wave reflection. The reproducibility of CSP and CSPTI is similar to that of PSP. CAI and the difference between PSP and CSP is not influenced by order of measurement, of visit or by investigator. Therefore, CAI is a more stable parameter than PSP measured by an oscillometric device. Since these parameters may contribute to a better assessment of cardiovascular risk, PWA might be used in prospective studies.

SummaryIn the Czech Republic, canine dirofilarial infection (Dirofilaria immitis and D. repens) is usually diagnosed in dogs coming from endemic areas and as such has been considered an imported infection. Here, 77 dogs that had never travelled abroad from the Břeclav area, close to Slovak border, were tested for Dirofilaria spp. infection. The presence of microfilaria in peripheral blood was detected by Knott test. Microfilariae were further examined by acid phosphatase staining and molecular methods (PCR). The presence of adult female D. immitis circulating antigens in blood was assessed by a commercial kit (PetChek, IDEXX Laboratories, Portland, USA). Microfilariae were detected in 7 (9 %) out of the 77 animals by the Knott test. The result of the acid phosphatase staining and PCR for all seven samples agreed with Dirofilaria repens species. Other five dogs of the 77 sera (6.5 %) sampled were serologically positive for circulating D. immitis antigens. No D. immitis microfilariae were found in these five dogs. D. repens positive dogs were negative on the ELISA for D. immitis. This is the first report of autochthonous cases of heartworm disease and subcutaneous dirofilariosis in dogs in the Czech Republic.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
