"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)"

"This cross sectional study was conducted on 304 elderly, aged 55 years and over, who were randomly selected at the Public Health Center levels in South Jakarta. The prevalence of CHD risk factors for the total population indicated by dyslipidemia and abdominal over fatness in this study were high (76% and 48°1o, respectively). Differences between gender were found with respect to body fat distribution as determinant of serum lipid profiles. In the elderly women, AHR were positively correlated with serum triglycerides and total cholesterol (p<0.05) but not in the elderly men. Energy, fat and cholesterol intakes did not show correlation with any serum lipid status in this population group. Energy intake of the elderly was low. Percent energy from fat and cholesterol intake were in accordance with the Indonesian Consensus of Dyslipidemia and NCEP (National Cholesterol Education Program). Generally, the elderly men and women had similar scores for several aspects of later life status. However cognitive function, well being, and later life status in the elderly men were higher than those in the elderly women. It was demonstrated that there was a significant negative association between physical activity score and selected serum lipid profiles (TC and TG), especially in the elderly women. Similar findings were also observed for social activity scores. No associations were found between alcohol consumption and serum lipid profiles in this study. On the other hand, smoking which was prevalent in the elderly men contributed to the elevation of serum triglycerides concentration. "

"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.
