Special Issue Information

Dear Colleagues,

The myocardial function is important in dogs and cats with heart disease, especially in dogs with myxomatous mitral valve disease who develop myocardial dysfunction at the congestive heart failure stage conjunction with hemodynamic dysfunction. Cardiomyopathy in dogs and cats is thought to be primarily caused by myocardial lesions, possibly involving the deterioration of the myocardial function. To date, various echocardiographic applications, including tissue Doppler, and newly developed speckle tracking techniques capable of quantifying the myocardial function have been demonstrated in dogs and cats with heart disease. Additionally, cardiac biomarkers, including natriuretic peptide and troponin measurements, have also begun to spread, these indices possibly being useful tools for the detection of myocardial dysfunction in dogs and cats.

This Special Issue aims to focus on myocardial function in dogs and cats with heart disease, welcoming original research articles, reviews, and case reports. Research areas may include, but are not limited to, the following: cardiology, echocardiography, electrocardiography, cardiac biomarkers, newly developed cardiology diagnostic tools, cardiac physiology, cardiovascular pharmacology, and comparative pathology.

I look forward to receiving your contributions.

Dr. Ryohei Suzuki

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Veterinary Sciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

An 11-year-old intact female Papillion weighing 2.1 kg was referred to our institution with the main complaint of shallow, rapid breathing. At the first visit (day 0), although clinical signs improved due to the use of medication from the primary hospital, transthoracic radiography and echocardiography revealed left heart enlargement and left ventricular dysfunction. A clinical diagnosis of dilated cardiomyopathy (DCM) was made and oral administration of pimobendan, temocapril, and taurine was initiated. However, on day 10, the respiratory status worsened and furosemide was prescribed. On day 54, no significant improvement in heart size was observed. Additionally, the diet that this patient received met the recommendation for diet-related DCM by the U.S. Food and Drug Administration, and the patient’s diet was changed from a grain-free diet to a grain-containing diet. On day 1191, the patient’s respiratory status was stable and no clinical signs were observed. Transthoracic radiography and echocardiography revealed an improvement in left heart size. Additionally, improvements in the left and right ventricular myocardial strains were observed after changing the diet. We suggest that it may be necessary to suspect a dietary association with dilated cardiomyopathy, and a good prognosis might be expected by dietary modification, even in small-breed dogs.
