In Thıs study, we aım to evaluate the erectile status of male patients undergoing percutaneous coronary intervention after both heart attack ( group 1) and stable angina ( Group 2). The primary aim is to assess any possible predictive effect of erectile function status on cardiac events. The secondary aim is to assess the direct effect of myocardial infarction on ED status by comparing the two groups. The secondary objective is to assess and analyse other determinants in the natural history survey of erectile status after the intervention. All male patients who undergo a successful PCI and survive will be evaluated. Patients who have had: Malignancy, underlying neurological diagnosis interfering with erectile status, uncontrolled diabetes, and more than two chronic medical conditions, on polifarmacy ( more than three medications a day), and no sexual relationship, who have not agreed to include the study, will not be included in the study. The follow-up period will be 0 (the time the patient recovered well after the intervention). Questinnaiere will examine the status over the last 3 months. 3 and 6-month follow-up. During the follow-up period, the interviews will be conducted face-to-face in the clinical environment, either by a responsible doctor or an educated nurse. The surveys include: IIEF (International Index of erectile function ) questionnaires BECK depression inventory questionnaires FCRP ( Fear of Cardiac Recurrence and Progression Scale ) The objective scale we use: Age SYNTAX score and residual SYNTAX score for evaluating the cardiac vessels occlusion status Cardiac Ejection Fraction status Laboratory values, including testosterone levels, Bodily measurements, including body mass index and waist circumference. Medications Medical conditions Intervention route ( trans radial or femoral ) The survey will take place in our institutions. The hypothesis is that erectile dysfunction is a preliminary condition of an upcoming cardiac event. Myocardial infarction causes significant changes in erectile function in a natural survey. The syntax score has a direct correlation with the baseline erectile function Residual syntax score has a direct relation with post-intervention erectile status.

Lp(a) levels play an important role in predicting subsequent ischemic events in patients with established coronary artery disease (CAD), especially those who underwent PCI. However, there are still no approved pharmacologic therapies that specifically target high Lp(a) levels. DAPT consisting of aspirin and a P2Y12 receptor inhibitor represents the cornerstone of pharmacological treatment aimed at preventing thrombotic complications after PCI. Considering that Lp(a) has a prothrombotic effect through its inactive, plasminogen-like protease domain on apo(a), the investigators speculate that prolonged DAPT may have a beneficial effect on reducing future ischemic events in patients with elevated Lp(a) levels after PCI. Some observational studies revealed that DAPT \> 1 year was significantly associated with lower risk of cardiovascular events compared with DAPT ≤ 1 year in patients with elevated Lp(a) levels who were event-free at 1 year after PCI with DES. However, the relative efficacy and safety of prolonged DAPT versus standard DAPT in this high-risk population has never been assessed in randomized controlled trials (RCTs). The DAPT-Lp(a) trial is a multicenter, parallel-group, randomized controlled trial with blinded end-point evaluation. Consecutive patients with Lp(a) levels\>30mg/dL who meet the inclusion criteria and none of the exclusion criteria will be randomized in a 1:1 fashion to 24-month DAPT group or 12-month DAPT group. The investigators hypothesise that, in patients with Lp(a) levels \>30mg/dL who were event-free at 1 year after PCI with DES, 24-month DAPT is superior to 12-month DAPT with respect to major adverse cardiovascular and cerebrovascular events (primary end point), while it is non-inferior to 12-month DAPT with respect to net adverse clinical events (key secondary end point). The investigators estimated that 3,300 patients would be needed to provide the necessary number of confirmed endpoints to test the study hypothesis. Patients will be followed up at 3, 6, 9, 12 months after randomization. All analyses will be performed according to the intention-to-treat (ITT) principle.

This is a registered prospective study that consecutively enrolled patients who were diagnosed with acute myocardial infarction (AMI) and underwent primary percutaneous coronary intervention (PCI) at Zhongshan Hospital, Fudan University, from January 2009 to December 2028. The study recorded each patient's baseline demographics, clinical history, physical examination data, laboratory results, medication usage, and procedural details. The predefined clinical endpoints include both in-hospital and long-term follow-up events. The former encompasses major adverse cardiovascular and cerebrovascular events (MACCE) composed of all-cause death, recurrent myocardial infarction, ischemia-driven repeat revascularization, malignant arrhythmias, acute heart failure, cardiogenic shock, and cerebrovascular accidents, as well as various bleeding events, gout flares, and intraoperative microcirculatory perfusion status during PCI. The latter includes MACCE composed of all-cause death, recurrent myocardial infarction, ischemia-driven repeat revascularization, readmission for acute heart failure, and cerebrovascular accidents, as well as changes in cardiac function during long-term follow-up. The occurrence of malignant tumors was designated as a falsification endpoint to assess the potential impact of confounding factors.

A comprehensive evaluation of the degree of coronary artery stenosis, myocardial ischemia range, and survival status are required before surgery, which can help predict postoperative efficacy and select the best treatment plan. Only when the heart muscle is alive, can the myocardial blood flow return to normal after revascularization surgery, improving left ventricular ejection fraction (LVEF) and long-term survival rate of patients. Performing coronary artery bypass grafting(CABG) on patients with lack of myocardial activity not only cannot benefit them, but also increases the risk of surgery. At present, the combination of 18F-flurodeoxyglucose(FDG) Positron Emission Tomography/ Computed Tomography(PET/CT) imaging and myocardial perfusion imaging is the most commonly used method in clinical practice to determine myocardial activity based on the matching of metabolism and blood flow. In recent years, the value of Cardiovascular Magnetic Resonance(CMR) in ischemic diagnosis and myocardial infarction assessment has been widely clinically validated, and many techniques in CMR have been included in clinical guidelines. Late Gadolinium Enhancement(LGE) imaging is the most accurate non-invasive technique for evaluating myocardial scars currently. Integrated Positron Emission Tomography/Magnetic Resonance imaging(PET/MR) can simultaneously evaluate myocardial perfusion, metabolism, vitality, and function, which has certain value for the diagnosis of myocardial ischemia and clinical prognosis of revascularization surgery.

Uganda faces a growing challenge of non-communicable diseases (NCDs) alongside the existing burden due to HIV/AIDS. By NCDs, the investigators refer to common conditions such as diabetes, cancers, and cardiovascular diseases (including hypertension, stroke, and heart attack). About 38.8% of the population in Uganda has raised blood pressure (pre-hypertension), 34% in urban and 22% in rural areas have hypertension. The risk factors, such as unhealthy diet and physical inactivity, responsible for the development of these NCDs are modifiable and related to behaviour. The investigators propose to adapt, implement and evaluate a family-centred approach to enhance behaviour change among adolescents and their families. Why focus on Adolescents? The investigators recognize that adolescence is a critical stage marked by significant physical, cognitive, and social changes and time to adopt behaviour that extends into adulthood. Previous studies have shown that even if the signs and symptoms of cardiovascular disease appear in adulthood, the process starts earlier during adolescence. The investigators aim to intervene by working with adolescents and families to change their behaviors and adopt a healthier diet and engage in recommended level of physical. The iHealth T2D study that was conducted in parts of Asia and the United Kingdom showed that using the family centered approach and working closely with community health care workers led to reduction in body weight, blood pressure and thus reducing the risk of NCDs among the Asian population. The investigators will adapt the iHealth T2D study intervention to the Ugandan context, considering the specific features of the setting, village health team responsibilities and content of the education material. The intervention will promote physical activity and healthy eating habits among families. The study comprises three phases; a) formative phase which is focusing on adapting the intervention, b) Implementation phase, to implement the adapted intervention and c) evaluation phase, assessing effectiveness and the overall process of the adapted intervention.
