COPD is a progressive pulmonary disease that is characterized by an inflammatory process in the airways and the lungs which leads to progressive airway obstruction. The inflammation is associated with tissue loss and remodelling. The investigators hypothesized that doxycycline reduces neutrophilic airway inflammation in patients with COPD. Therefore the investigators will conduct a randomized trial of doxycycline in 30 patients.

Objective: Untreated OSA is associated with three fold risk of fetal and non-fetal cardiovascular events than control subjects in the long-term follow up. However, the prevalence rate and impact of OSA in patients with acute myocardial infarction (AMI) was not clear so far. The conflicts of studies come from variable period of AMI, heart function at enrollment, techniques used to diagnose OSA, time to revascularization, and target endpoint. Therefore, this project aimed to study the patients of first-time, Killip I-II, and post primary percutaneous coronary intervention (PCI) AMI in both and chronic phase to achieve four goals: Aim 1. To determine the prevalence rate of OSA in patients with first-time AMI The acute phase of AMI was defined as within 14 days of the onset of AMI and the chronic phase was defined as \> 14 days of onset. Eligible patients were screened with polysomnography within 5th to 7th days and 6th months of AMI to determine the prevalence rate of OSA in the AMI. Patients who had AHI more than 15/hr were considered as suffering from OSA. Aim 2. To identify the clinical characteristics and risk factors in AMI patients associated with OSA Patients were followed up at clinics for five years. The baseline demographics of patients with or without OSA were compared to determine the factors associated with OSA in AMI patients. Aim 3. To study the impact of OSA on the prognosis of AMI patients after revascularizaton The primary endpoint was mortality rate and cardiac events. The secondary endpoint was left ventricular function and variables related to cardiovascular disease (CVD) and metabolic syndrome. The impact of OSA on AMI was determined by comparing primary and secondary endpoint between AMI patients with and without OSA. Aim 4. To identify the clinical and molecular factors attributing to AMI in OSA patients Factors attributing to AMI in OSA patients were determined by comparing the clinical data and mRNA expression of angiogenesis and other related genes in OSA patients with the acute phase of AMI and patients without major CVD.
