Cardiovascular effects of ophthalmic 0.5% timolol aqueous solution and 0.1% timolol hydrogel

Autor: J, Niño, K, Tahvanainen, H, Uusitalo, V, Turjanmaa, N, Hutri-Kähönen, T, Kaila, A, Ropo, T, Kuusela, M, Kähönen

Publikováno v: Clinical physiology and functional imaging. 22(4)

The objective of this randomized, double-masked, cross-over study was to compare the cardiovascular effects of two glaucoma formulations, ophthalmic 0.5% timolol aqueous solution and 0.1% timolol hydrogel. Twenty-four young healthy subjects received

Publikováno v: European Radiology. 5

Iodixanol (320 mg I/ml) was compared with iopromide (370 mg I/ml) in a double-masked, parallel group, randomised trial of 120 patients undergoing cardioangiography in order to evaluate and compare safety, tolerability and radiographic efficacy. The o

Myocardial sympathetic nervous dysfunction detected with iodine-123-MIBG is associated with low heart rate variability after myocardial infarction

Autor: M, Mäntysaari, J, Kuikka, J, Hartikainen, J, Mustonen, H, Mussalo, K, Tahvanainen, E, Länsimies, M, Uusitupa, K, Pyörälä

Publikováno v: Journal of nuclear medicine : official publication, Society of Nuclear Medicine. 36(6)

The association between myocardial sympathetic innervation and heart rate variability after myocardial infarction was studied in a group of 12 men (aged 30-65 yr) 3 mo after their first myocardial infarction.Viable myocardium was imaged using 123I-ph

Publikováno v: Advances in space research : the official journal of the Committee on Space Research (COSPAR). 12(1)

A microcomputer-based system for non-invasive monitoring of cardiovascular system in simulated microgravity is described. The system evaluates automatically, accurately and interactively heart beat intervals, beat-to-beat non-invasive finger arterial
