Patient description: A 45-year-old woman was referred to the emergency department with abdominal pain lasting about 4 days accompanied by nausea and 2 episodes of vomiting. The pain is localized to the epigastric region and radiates to the right upper quadrant. The pain is worsening after eating fatty food. The patient experienced similar pain twice in the past year. Her past medical history is remarkable for hypercholesterolemia and two C/sections. She has 2 children, and she is menopausal. She doesn't smoke, drink alcohol, or use illicit drugs. She is mildly febrile. Her BP is 150/85, HR 115, RR 15, T 38.2, SpO2 98% on RA. On palpation, she experiences epigastric tenderness and tenderness in the right upper quadrant without rebound. Bowel sounds are normal. Laboratory analysis is remarkable for elevated ESR and leukocytosis with a left shift. The ultrasound revealed several gallstones and biliary sludge. The largest gallstone is 0.7cm. Surgery consultation recommends elective cholecystectomy.

Clinical trial eligibility criteria: eligible ages (years): 35.0-55.0,  Acute Coronary Syndrome Periodontitis for ACS group : • Patients diagnosed with both ACS and localized or generalized periodontitis of stage II or III with grade B or C. ACS patients myocardial infarction (NSTEMI), and ST-segment elevation myocardial infarction (STEMI) were hospitalized . Unstable angina (UA) was defined as the new onset or a changed pattern of angina over the past 2 months and Canadian Cardiovascular Society (CCS) class IV angina at the time of presentation coinciding with appropriate objective evidence of myocardial ischemia on an electrocardiogram (ECG) or myocardial perfusion imaging. ACS with ST-segment elevation was defined as AMI characterized by: chest pain, radiating or not to the upper extremities, lower jaw, upper back or epigastrium lasting 30 minutes or more, associated or not with sweating, nausea or pallor; presence of ST-segment elevation of 1 mm in two or more contiguous peripheral leads or 2 mm in two or more contiguous precordial leads on electrocardiogram (ECG); and elevation in serum markers of myocardial injury and necrosis (CK, CK-MB) three times their reference value28. Non-ST-segment elevation ACS on ECG was defined as a clinical condition similar to that mentioned above but with chest pain lasting less than 30 minutes, with or without elevation of serum enzyme markers of myocardial injury and necrosis (CK, CK-MB, cardiac troponins I and T). ACS patients were referred to the Department of Periodontology, Faculty of Dentistry, Selcuk University (Konya/Turkey) for periodontal examination in a one year period. for control group : • Patients diagnosed with localized or generalized periodontitis of stage II or III with grade B or C. Twenty-six age and sex-matched patients (43.04±8.35 years) with periodontitis (Group P) otherwise systemically healthy were recruited as control group in the Department of Periodontology, Faculty of Dentistry, Selcuk University (Konya/Turkey). Exclusions for both groups included metabolic disorders high blood pressure treated with antihypertensive medications periodontal therapy antibiotic treatment until 3 months prior the study. Smoking habits and education status were also recorded. ACS patients take aspirin (1 × 100 mg per day) during 1 month
