<![CDATA[Penyakit arteri koroner (PAK) ditandai lesi aterosklerosis yang menyebabkan penurunan suplai oksigen ke miokardium. Sebagian pasien PAK membentuk pembuluh kolateral yang menambah suplai darah ke miokardium. Pembentukan kolateral didasari proses angiogenesis dan dipengaruhi oleh berbagai faktor. Aspirin telah digunakan sebagai pencegahan angiogenesis. Penelitian ini bertujuan mencari pengaruh faktor klinis dan pengobatan terhadap pembentukan kolateral koroner. Penelitian ini menggunakan metode potong lintang pada pasien PAK yang dilakukan angiografi koroner. Klasifikasi kolateral koroner dinilai menggunakan kriteria Rentrop. Subjek penelitian dibagi menjadi kolateral baik dan kolateral buruk, ditentukan berdasar atas penilaian intervensionis. Faktor yang dianalisis adalah keluhan angina, obat-obatan, lesi stenosis, dan faktor risiko kardiovaskular. Analisis statistik menggunakan korelasi Spearman dan regresi logistik. Sebanyak 382 pasien diikutsertakan dalam penelitian. Seluruh subjek penelitian memiliki stenosis koroner di atas 80% pada salah satu arteri koroner. Analisis kolateral koroner mendapatkan 164 pasien kolateral baik dan 158 orang kolateral buruk. Secara bivariat, faktor-faktor yang berpengaruh pada pembentukan kolateral koroner yang buruk adalah: penggunaan inhibitor ACE (p=0,048), penggunaan aspirin (p=0,047), oklusi pada pembuluh left circumflex (p=0,032), tidak ada keluhan angina (p=0,036), dan diabetes (p=0,047). Regresi logistik tidak menunjukkan kemaknaan dari faktor-faktor diatas terhadap pembentukan kolateral koroner (p=0,088). Penelitian ini menyimpulkan bahwa aspirin, inhibitor ACE, oklusi pembuluh left circumflex, tidak ada keluhan angina dan riwayat diabetes memiliki potensi untuk menghambat pembentukan kolateral koroner.

Some CAD patients develop collaterals which augment myocardial blood circulation. Angiogenesis is a precursor for collateral development and influenced by multiple factors. Aspirin has been used as an angiogenesis inhibitor. This study was intended to elucidate clinical and treatment factors that may affect collateral development. This study employed cross-sectional methodology. Subjects were CAD patients who underwent coronary angiography. Grading of coronary collaterals was classified using Rentrop criteria. Subjects were categorized into poor collaterals and good collaterals, determined by an interventionist. Factors analyzed were anginal symptoms, medications, stenotic lesions, and cardiovascular risk factors. Data were examined using Pearson or Spearman correlation and logistic regression. A total of 382 patients were selected. All subjects had 80% or more stenotic lesions in one or more coronary arteries. There were 164 patients assigned as good collaterals and 158 patients was assigned as poor collaterals. Factors that hampered collateral development were: ACE (p=0.048) and aspirin (p=0.047) use, occlusion of left circumflex artery (p=0.032), no anginal symptoms (p=0.036) and diabetics (p=0,047). None of these factors was statistically significant in logistic regression (p=0.088). The study concluded that aspirin has a potential to diminish coronary collateral development.
