Cardiovascular disease, particularly Coronary Heart Disease (CHD), complicated by Coronary Heart Failure (CHF), is the main cause of the disability and mortality through of the world. Earlier disease reveal presents the major medical strategy policy in the disease management. Chronic CHF is the most occasions presented the latest stage of the cardiovascular disease evaluation. It presents one of the widespread syndromes (2% in adults population) as an extremely serious health condition and appears to cause hospitalization of the patients above 65 years age. Thus, the right way in that group of the patients treatment have to be chosen in the medical policy, using the satisfacted disease classification. Aim: To choose more convenient and assessable criteria of the CHF evaluation 6-minute’s walk-test have been implemented in patient with CHF as an additional criteria in NYHA classification. Materials and methods: The walk-test has been performed in 23 patients aged 35-70 years. The investigation criteria have been chosen as follows: CHF functional class III-IY, having CHF diagnosis at least 3 months prior the examination, EF less than 40%, stable health condition under the basic treatment during the one week ( diuretics, B-blockers, ACE-inhibitors). The 6-minutes walk-test is applied to detect and identify the physical tolerance under the load in patients with CHF to choose the critical load index, as discordance between the physical efforts and physiological parameters, which will be assessed as the nonadequate blood circulation reaction to the accomplished load. The patient’s health conditions have been evaluated taken in consideration-covered distance in the test period. Body weight have to be taken in consideration as well as CHD risk factor and having connection to walking speed, neither sex which does not have any influence on the test results.
Results: Working ability of the patients with NYHA class III-IV CHF, whose EF varies level between 40-21%, is lowered resulted in short distance by them in six minute (170-100 meters) as well as in panting, breathlessness and strong tachycardia. Five cases were recorded when the patient were unable to accomplish the test due to the presence of above-mentioned symptoms and test was stopped. Conclusion: According to the obtained data it have to be note that 6-minutes walk-test gives the possibility to evaluate an initial CHF as well to manage medical care process. |
