Aortic stenosis with abnormal eccentric left ventricular remodeling secondary to hypothyroidism in a Bourdeaux Mastiff Ciência Rural
Minozzo,Guilherme Augusto; Stedile,Simone Tostes de Oliveira; Sousa,Marlos Gonçalves.
ABSTRACT: This paper describes a case of congenital aortic stenosis with eccentric left ventricular hypertrophy associated with hypothyroidism in a 1-year-old Bourdeaux Mastiff dog. The dog had ascites, apathy, alopecic and erythematous skin lesions in different parts of the body. A two-dimensional echocardiogram revealed aortic valve stenosis, with poststenotic dilation in the ascending aorta. The same exam showed eccentric hypertrophy and dilation of the left ventricle during systole and diastole. Aortic stenosis usually results in concentric left ventricular hypertrophy instead of eccentric hypertrophy; and therefore, this finding was very unusual. Hypothyroidism, which is uncommon in young dogs, may be incriminated as the cause of ventricular dilation,...

Effect of exercise training on ventilatory efficiency in patients with heart disease: a review BJMBR
Prado,D.M.L.; Rocco,E.A.; Silva,A.G.; Rocco,D.F.; Pacheco,M.T.; Furlan,V..
The analysis of ventilatory efficiency in cardiopulmonary exercise testing has proven useful for assessing the presence and severity of cardiorespiratory diseases. During exercise, efficient pulmonary gas exchange is characterized by uniform matching of lung ventilation with perfusion. By contrast, mismatching is marked by inefficient pulmonary gas exchange, requiring increased ventilation for a given CO2 production. The etiology of increased and inefficient ventilatory response to exercise in heart disease is multifactorial, involving both peripheral and central mechanisms. Exercise training has been recommended as non-pharmacological treatment for patients with different chronic cardiopulmonary diseases. In this respect, previous studies have reported...

Health Disparities in Rural Georgia: A Case Study of Liberty, Long, and McIntosh Counties AgEcon
Amponsah, William A.; Fuller, Whitney; Gibbison, Godfrey.
Health disparities can be defined as differences in the health status among distinct segments of the population including differences that occur by gender, race or ethnicity, education, income, disability, or living in various geographic localities. When populations are disproportionately unhealthy, they are likely to be unable to maintain steady employment, and are more likely to rely on government assistance and support from others. We conduct a case study of three rural counties; Liberty, Long, and McIntosh to explore what factors explain the incidence of health disparities manifested in high blood pressure and heart disease. We test the hypotheses that older individuals are more likely to experience illness at a higher rate than the rest of the...

Mannose-binding lectin 2 (Mbl2) gene polymorphisms are related to protein plasma levels, but not to heart disease and infection by Chlamydia BJMBR
Queiroz,M.A.F.; Gomes,S.T.M.; Almeida,N.C.C.; Souza,M.I.M.; Costa,S.R.C.F.; Hermes,R.B.; Lima,S.S.; Zaninotto,M.M.; Fossa,M.A.A.; Maneschy,M.A.; Martins-Feitosa,R.N.; Azevedo,V.N.; Machado,L.F.A.; Ishak,M.O.G.; Ishak,R.; Vallinoto,A.C.R..
The presence of the single nucleotide polymorphisms in exon 1 of the mannose-binding lectin 2 (MBL2) gene was evaluated in a sample of 159 patients undergoing coronary artery bypass surgery (71 patients undergoing valve replacement surgery and 300 control subjects) to investigate a possible association between polymorphisms and heart disease with Chlamydia infection. The identification of the alleles B and D was performed using real time polymerase chain reaction (PCR) and of the allele C was accomplished through PCR assays followed by digestion with the restriction enzyme. The comparative analysis of allelic and genotypic frequencies between the three groups did not reveal any significant difference, even when related to previous Chlamydia infection....

Radiographic Evaluation of Caudal Vena Cava Size as a Useful Parameter for the Diagnosis of Heart Disease in Dairy Cattle OAK
Jilintai; Hashiyama, Sayaka; Gonda, Yuhsuke; Ishikawa, Hiroshi; Sato, Motoyoshi; Miyahara, Kazuro.
To quantify the radiographic parameters of the caudal vena cava (CVC) in healthy cattle and demonstrate their clinical usefulness, the present study compared the ratios of the diameter of the thoracic CVC to the diameter of the aorta (Ao) and length of the thoracic vertebrae (VL), which are all positioned in the same intercostal space, in 81 healthy control cattle (43 growing, 38 adult) and 10 cattle with heart disease. The average diameter of the CVC (CVCave) was correlated with the size of the Ao and VL in the control cows. Although the diameter and pulsation index of the CVC differed significantly between the growing and adult cows, the ratios of CVC/Ao and CVC/VL were fixed values for both the growing and mature cattle. However, in the cattle with...
