Restrictive Cardiomyopathy
Feline restrictive cardiomyopathy
Juga dikenal sebagai: RCM, Feline Restrictive Cardiomyopathy, Endomyocardial Fibrosis
Singkatnya
Restrictive cardiomyopathy (RCM) is an uncommon but serious feline heart disease characterized by stiffening of the heart muscle. This stiffness prevents the heart from filling properly, leading to congestive heart failure and a high risk of blood clots. Learn the signs, how vets diagnose it, and what to expect.
TL;DR. Penyakit jantung kucing progresif: jaringan parut membuat ruang jantung kaku, menghambat pengisian, dan sering menyebabkan gagal jantung atau bekuan darah.
Fibrosis membuat dinding kaku; atrium kiri sering sangat membesar.
Apa itu?
RCM jarang tetapi serius. Berbeda dari HCM (dinding tebal), intinya kekakuan ekstrem karena fibrosis: disfungsi diastolik, penumpukan ke atrium kiri, edema/efusi, risiko tromboemboli tinggi.
Based on this classification scheme, there are four basic types of cardiomyopathy: (1) dilated cardiomyopathy, (2) hypertrophic cardiomyopathy (HCM), (3) restrictive cardiomyopathy (RCM), and (4) arrhythmogenic right ventricular cardiomyopathy. All these forms are observed in the cat.
Bentuk miokardial dan endomiokardial.
Penyebab dan faktor risiko
Idiopatik, kemungkinan multifaktorial.
Restrictive cardiomyopathy (RCM) is associated with extensive endocardial, subendocardial, or myocardial fibrosis of unclear, but probably multifactorial, cause.
Kucing dewasa hingga tua; tanpa predisposisi ras yang terdokumentasi.
Tanda
- Dispnea, takipnea, bernapas mulut terbuka (umum)
- Tidak aktif, anoreksia, penurunan berat, muntah (umum)
- Distensi vena jugularis (umum)
- Tromboemboli / saddle thrombus (umum dan darurat)
- Murmur, gallop, aritmia (kadang)
Usaha napas yang meningkat memperingatkan gagal jantung kongestif.
Diagnostik
Ekokardiografi (baku emas): atrium kiri besar, ketebalan dinding hampir normal, pengisian kaku. Rontgen dada, EKG.
Pengobatan
Tidak ada obat yang menghilangkan fibrosis. Diuretik, ACEI, antiplatelet (clopidogrel), antiaritmia jika perlu. Pantau frekuensi napas istirahat.
Prognosis
Hati-hati hingga buruk; progresif. Dengan deteksi dini, beberapa bulan hingga >1 tahun kenyamanan mungkin.
Pencegahan
Tanpa pencegahan primer. Pemeriksaan rutin; murmur/gallop/aritmia dievaluasi.
Kapan menghubungi dokter hewan
Segera jika frekuensi napas istirahat >30–40/menit, napas mulut terbuka, kelumpuhan kaki belakang, telapak kaki dingin, kolaps, atau anoreksia total.
