Cardiac Disease and Screening in Breeding Dogs
1Department of Small Animal Clinical Sciences, University of Florida College of Veterinary Medicine, 2015 Southwest 16th Avenue, Gainesville, FL 32610, USA.
Summary
Canine heart disease screening helps reduce prevalence, but breeding program success varies. Genetic factors and specific breed predispositions influence outcomes in dogs with cardiac conditions.
Area of Science:
- Veterinary Cardiology
- Canine Genetics
Background:
- Acquired and congenital heart diseases are common in dogs, with breed-specific predispositions.
- Genetic causes and inheritance patterns for several canine cardiac diseases are known.
- Breed screening is a strategy to decrease the incidence of heart disease in dogs.
Purpose of the Study:
- To review the effectiveness of breed screening in managing canine cardiac diseases.
- To highlight the variability in outcomes of breeding programs aimed at reducing heart disease.
Main Methods:
- Literature review on canine cardiac diseases and genetic inheritance.
- Analysis of breed screening effectiveness and breeding program outcomes.
- Examination of factors influencing the success of cardiac disease reduction strategies.
Main Results:
- Breed screening shows potential in reducing the prevalence of certain canine heart conditions.
- The success of specific breeding programs is inconsistent and influenced by various factors.
- Understanding genetic causes is crucial for effective disease management.
Conclusions:
- While breed screening can be beneficial, its impact on canine heart disease prevalence is variable.
- Multiple factors contribute to the variable outcomes observed in canine breeding programs for cardiac health.
- Further research into genetic predispositions and breeding strategies is warranted.

01:20Imaging Studies for Cardiovascular System III: X-Ray
219
The most common cardiovascular diagnostic test is an X-ray. It produces images of the heart, blood vessels, and adjacent structures.
Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...

42
Dysrhythmias, also known as arrhythmias, are disturbances in the heart's rhythm that range from benign to life-threatening. A thorough evaluation is crucial for appropriate management and involves a comprehensive medical history, physical examination, and various diagnostic tests.Medical HistorySymptoms: Collect detailed information on palpitations, dizziness, syncope, chest pain, and fatigue. Note their onset, frequency, and triggers.Previous Cardiac Issues: Document any history of heart...

Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

01:43Incomplete Dominance
22.9K
Gregor Mendel's work (1822 - 1884) was primarily focused on pea plants. Through his initial experiments, he determined that every gene in a diploid cell has two variants called alleles inherited from each parent. He suggested that amongst these two alleles, one allele is dominant in character and the other recessive. The combination of alleles determines the phenotype of a gene in an organism.

Coronary Artery Disease (CAD): An Overview with Scientific InsightsCoronary Artery Disease (CAD), often referred to as C-A-D, is a prevalent blood vessel disorder classified under the broader category of atherosclerosis. Atherosclerosis is a pathological process characterized by the hardening and narrowing of arteries due to the accumulation of atherosclerotic plaques. These plaques are composed of cholesterol, fatty substances, inflammatory cells, calcium, and fibrin, reducing blood flow to...

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...
