"Aterosklerosis sampai saat ini merupakan penyebab utama morbiditas dan mortalitas di negara maju. Meskipun modifikasi faktor risiko di negara maju telah dapat menurunkan kekerapan aterosklerosis namun penurunan ini mulai menunjukkan grafik yang mendatar. Keadaan ini merangsang para peneliti untuk mencari faktor pajanan lingkungan termasuk faktor infeksi yang dapat mempengaruhi proses aterosklerosis. Telah dilakukan penelitian potong lintang dari bulan Maret 1998 sampai Agustus 1998 terhadap 122 orang pasien yang secara klinis menunjukkan penyakit jantung koroner yang menjalani kateterisasi jantung, terdiri dari 92 orang laki-laki dan 30 orang perempuan dengan rerata umur 55 tahun. Pasien diperiksa secara klinis dan laboratorium (gula darah, kolesterol, trigliserida dan antibodi terhadap C.pneumoniae, Cytomegalovirus dan H.pylori). Pada penelitian ini didapatkan perbedaan kadar kolesterol, trigliserida dan HDL antara kelompok stenosis koroner dan non stenosis. Sedangkan kadar antibodi C.pneumoniae, Cytomegalovirus, H.pylori tidak berbeda bermakna. Penelitian ini belum dapat menyimpulkan pengaruh antibodi terhadap aterosklerosis karena pada kelompok non stenosis tidak dapat disingkirkan kemungkinan terjadinya aterosklerosis mengingat rerata umur subyek penelitian 55 tahun. Penelitian mengenai interaksi infeksi dengan risiko tradisional serta gender dan nutrisi diperlukan untuk mendapat jawaban yang lebih jelas tentang pengaruh infeksi terhadap aterosklerosis.

Atherosclerosis is still the chief cause of morbidity and mortality in developed nations. Even though in developed nations the modification of risk factors is able to reduce the prevalence rate of atherosclerosis, such reduction is starting to slow down. Such condition has stimulated researchers to identify environmental exposure, including infection, that can influence the process of atherosclerosis. This cross sectional study was conducted from March to August 1998, on 122 patients that clinically demonstrate coronary heart disease and have underwent cardiac catheterization, 92 males and 30 females with an average age of 55 years. Patients undergo clinical and laboratory evaluation (blood glucose, cholesterol, triglyceride, and antibody for C.pneumoniae. Cytomegalovirus, and H.pylori). We found a significant difference in cholesterol, triglyceride, and HDL levels in those with coronary stenosis and those without. However, we did not find a significant difference in the levels of C.pneumoniae, Cytomegalovirus, and H.pylori antibodies. This study is unable to conclude the influence of these antibodies on atherosclerosis, since in the non-stenosis group, we cannot eliminate the possibility of atherosclerosis, since the average age of study subject is 55 years. Studies on the interaction between infection and traditional risk factors as well as gender and nutrition is needed to find a clear answer of the influence of infection in atherosclerosis.

To determine the mean value of high sensitivity C-Reactive Protein (hs-CRP), association between plasma level of hs-CRP with extent of disease and systolic function. A cross sectional study had been conducted to 106 coronary artery disease patients (90 stable angina pectoris, 11 unstable angina pectoris and 5 acute myocardial infarction). Plasma quantitative level of hs-CRP with cor angiography to determine extent of disease and ejection fraction were measured. The mean of hs-CRP levels in patients with SVD were 5,5 ± 7,6 mg/L, DVD were 6,6 ± 21,7 mg/L and TVD were 5,5 ± 8,0 mg/L and p=0,056, respectively. There were no significant association between hs- CRP levels with extent of disease. Systolic function had negative correlation with levels of hs-CRP (p=0,015, r=-0,235). This study showed that plasma level of hs-CRP cannot reflect the extent of disease, and it had negative correlation with systolic function. (Med J Indones 2003; 12: 201-6)"

"Intracoronary thrombosis plays an important role in the pathogenesis of acute coronary syndrome. It occurs due to a rupture of an atherosclerotic plaque, which may be spontaneous, as in the case of acute coronary syndrome, or due to procedures such as percutaneous intervention (PCI). Atherosclerotic plaque rupture causes exposure of thrombogenic subendothelial components and initiates platelet aggregation, which then initiates the coagulation cascade. In stable angina, the formation of platelet thrombus is the most important tiling to occur on plaque progressiveness as a result of rupture and episodic formation of thrombi.' Arterial thrombi contain many platelets. Anti-platelet agents are greatly beneficial in acute and chronic coronary heart disease. This paper discusses the use of anti-platelet agents in coronary heart disease."

"Aterosklerosis sebagai penyebab terjadinya PJK merupakan proses multifaktorial karena banyak sekali faktor-faktor yang menyebabkannya dengan mekanisme yang saling terkait. Saat ini proses aterosklerosis dianggap sebagai proses inflamasi. Inflamasi terbukti berperan penting pada inisiasi, progresi maupun destabilisasi plak aterosklerosis. High sensitivity C-reactive protein (hs-CRP) merupakan salah satu petanda inflamasi yang penting pada penyakit jantung koroner (PJK) yang berhubungan dengan tingkat keparahan aterosklerosis, iskemi miokardium dan nekrosis miokardium. Tujuan penelitian ini adalah untuk mengetahui dan membandingkan kadar hs-CRP pada pasien sindroma koroner akut (SKA), PJK kronik dan bukan PJK, serta untuk mengetahui apakah terdapat hubungan antara kadar hs-CRP dengan kadar enzim CKMB pada pasien infark miokard akut (IMA). Penelitian bersifat observasional deskriptif dan analitik dengan pendekatan potong lintang. Dilakukan pemeriksaan kadar hs-CRP dengan metode chemiluminescent pada 21 pasien SKA, 20 pasien PJK kronik dan 20 bukan PJK. Didapatkan kadar hs-CRP rerata pada pasien SKA, PJK kronik dan bukan PJK sebesar 8,40 (SD 5,53) mg/l, 2,81 (SD 2,09) mg/l dan 1,07 (SD 0,81) mg/l. Analisis statistik didapatkan perbedaan kadar hs-CRP yang bermakna antara pasien SKA, PJK kronik dan bukan PJK (p 0,000). Kadar hs-CRP mempunyai korelasi positif yang bermakna dengan kadar enzim CKMB pada pasien IMA (p 0,004). Sebagai kesimpulan, kadar hs-CRP pada pasien SKA secara bermakna lebih tinggi dibanding PJK kronik dan bukan PJK. Terdapat hubungan yang bermakna antara peningkatan kadar hs-CRP dengan peningkatan kadar enzim CKMB. (Med J Indones 2004; 13: 102-6)

Coronary heart disease (CHD) due to atherosclerosis is a multifactorial process with multiple interdependent factors. At present time, atherosclerosis is considered to be an inflammatory process. It has been proven that inflammation plays a mayor role in the initiation, progression as well as the destabilitation of the atherosclerosis plaque. High sensitivity C-reactive protein (hs-CRP) is one of the most important inflammatory marker in CHD and directly related to the extent and severity of atherosclerosis, extent of myocardial ischemia and myocardial necrosis. The purpose of this study is to determine hs-CRP levels in patients with acute coronary syndrome (ACS), chronic CHD and non CHD. And, to determine the correlation between hs-CRP levels and CKMB enzyme level in patients with acute myocardial infarction (AMI). This is a descriptive observational analytic study with cross sectional design. hs-CRP levels were measured by using chemiluminescent method on 21 ACS patients, 20 chronic CHD patients and 20 non CHD patients. The mean hs-CRP level in ACS, chronic CHD and non CHD patients were respectively 8.40 (SD 5.53) mg/l, 2.81 (SD 2.09) mg/l and 1.07 (SD 0.81) mg/l. A statistically significant difference in hs-CRP level was found between ACS, chronic CHD and non CHD (p = 0.000 ). A positive correlation was found between hs-CRP level and CKMB enzyme level in AMI patients (p = 0.004). In conclusion hs-CRP level is consistently higher in patients with ACS compared to patients with chronic CHD and non CHD. A positive correlation was found between the increased level of hs-CRP and CKMB enzyme level. (Med J Indones 2004; 13: 102-6)"

Background: Epicardial adipose tissue (EAT) as part of visceral adipose tissue, has an integral role in the atherosclerotic cardiovascular disease. Previous studies have shown that EAT is thicker in those with coronary heart disease.

Objective: To determine the correlation of epicardial adipose thickness with the severity of coronary artery stenosis in stable coronary heart disease (CHD) patient.

Method: A cross-sectional study was conducted on seventy stable CHD patient undergoing coronary angiography. Severity of coronary artery stenosis was evaluated using Gensini scoring system : > 40 (severe) and ≤ 40 (mild-moderate). Epicardial adipose tissue was measured using transthoracic echocardiography at end-systole from parasternal longaxis view.

Results: Mean value of epicardial adipose thickness was 5,96 mm (SD 1,76) and median value of Gensini score was 35,0 (range 2-126). The correlation test showed a significant strong-positive correlation (r = 0,768, p < 0,001). The best cut-off point of epicardial adipose thickness which has a clinical value correlating to severity of coronary artery stenosis based on Gensini scoring system was 6,15 mm with the sensitivity 85,29 %, specificity 83,33%, positive predictive value 82 %, negative predictive value 85 % and AUC of 0,893 (CI 0,814-0,971, p < 0,001).

Conclusion: Epicardial fat thickness is significantly correlated to the severity of coronary artery stenosis based on Gensini scoring system. The thickness cutoff point of 6,15 mm has a good capability in discriminating mild-moderate dan severe stable CHD patient based on Gensini scoring system."
