Texas A&M cardiologists saved a beloved border collie from a third-degree atrioventricular block
Treating mitral regurgitation -damming up the spill (Proceedings)
October 1st 2011Studies have been performed in humans to determine if early administration of ACE inhibitors to human patients with ischemic dilated cardiomyopathy decreases the progression of myocardial failure and so reduces mortality.
Dilated cardiomyopathy-born under a bad sign (Proceedings)
October 1st 2011Dilated cardiomyopathy (DCM) is a cardiac disease due to an inherent abnormality in the myocardium that results in a decrease in myocardial contractility (i.e., myocardial failure) and is not secondary to another primary disease.
Etiology of Feline hypertrophic cardiomyopathy just b. cause (Proceedings)
October 1st 2011In humans, the familial nature of HCM was first reported in 1958. It has been demonstrated that over 70% of human cases of HCM are inherited in an autosomal dominant pattern, with most other cases being sporadic (although often still genetic in origin).
Hypertrophic cardiomyopathy--getting into the thick of it (Proceedings)
October 1st 2011Hypertrophic cardiomyopathy (HCM) is a primary myocardial disease that primarily affects left ventricular (LV) myocardium and is characterized by mild to severe thickening (concentric hypertrophy) of the LV wall (septum and/or free wall) and papillary muscles.
Facts and fiction about pulse oximetry (Proceedings)
October 1st 2011The gold standard for determining arterial blood gas levels is actually measuring arterial blood samples with a blood gas machine to get information on the arterial oxygen partial pressure (PaO2), pH and carbon dioxide partial pressure (PaCO2).
Murmurs in puppies and kittens (Proceedings)
August 1st 2011Congenital heart disease (CHD) is a morphologic defect of the heart or great vessels which is present at birth. "Congenital" does not imply the defect was inherited, although many CHD are heritable. CHD may also be caused by de novo spontaneous mutations, which have the potential to be transmitted to progeny. Diagnosis of CHD is important for the health of the patient and also to eliminate affected individuals from the breeding pool.
Get with the beat! Analyzing and treating cardiac arrhythmias (Proceedings)
August 1st 2011The primary indication for obtaining an electrocardiogram (ECG) is to evaluate an arrhythmia. Patients with a history of syncope, episodic weakness, or collapse should be evaluated with an ECG. An ECG is an insensitive test for assessment of specific cardiac chamber enlargement, and interpretation of structural heart disease is best done using radiography and echocardiography.
Collapsing dogs: managing common causes of collapse or syncope (Proceedings)
August 1st 2011Collapse and shock are a clinical manifestation of many different severe diseases, and requires emergency triage and care. Other dogs may present with a history of episodes of collapse and may be clinically stable on presentation. These two categories of patients are treated very differently, but they have some similar differential diagnoses.
Pericardial effusion: causes and clinical outcomes in dogs (Proceedings)
August 1st 2011Pericardial effusion is a fairly common acquired heart disease in dogs, and prevalence has been reported to be 0.43% (or 1 dog per 233 cases) of dogs presenting to a referral veterinary hospital, and accounts for approximately 7% of dogs with clinical signs of cardiac disease.1
Working up pleural effusions in cats (Proceedings)
August 1st 2011Cats presenting with pleural effusion are nearly always in respiratory distress, ranging from an increased respiratory rate and effort to open mouth breathing. In the latter situations, therapeutic intervention must be initiated quickly to prevent respiratory arrest. The therapeutic intervention also provides your first diagnostic test.
Thromboembolic disease (Proceedings)
August 1st 2011Thrombophilia (hypercoagulability or prothrombotic state) is a complex disorder with a diverse and multifactorial pathogenesis that results in a wide spectrum of clinical manifestations. It is well-recognized as a frequent and serious cause of morbidity and mortality in people. It appears less prevalent in dogs and cats for several reasons.
Heartworms in cats: new insights (Proceedings)
August 1st 2011A new study performed at Auburn University's College of Veterinary Medicine is radically changing our understanding of how heartworms affect the cat. In this study three groups of cats were studied for 8 and 16 months with antibody and antigen tests, radiographs of the heart and lungs, and necropsy examinations of the heart and lungs.
The silent killer: pulmonary hypertension (Proceedings)
August 1st 2011Pulmonary hypertension (PH) is defined by a systolic pulmonary artery pressure greater than 25 mmHg. The incidence of PH is difficult to define due to lack of clinical awareness, non-specific clinical signs, and difficulty in confirming the diagnosis.
