Stent as a Novel Technology for Coronary Artery Disease and Their Clinical Manifestation.

Coronary artery disease (CAD) is a cardiovascular disease of the blood vessels that makes vessels, narrow and hardened and difficult to supply blood to the heart. The epidemiology of CAD disease is a common clinical syndrome of a global health priority and the burden is increasing at an alarming rate worldwide. The prevalence of CAD not only increases mortality, morbidity and worsens the patient quality of life but also puts a huge burden on the overall healthcare system. The novel risk factors include: cholesterol level, cigarette smoking, diabetics, obesity, and hypertension, respectively are the causative agents of CAD. Furthermore, the etiology of CAD is also a very complex process and several interrelated etiological factors are involved in the pathogenesis of CAD. The signs and symptoms of CAD appear like angina, heart failure, and dyspnea, myocardial infarction, and arrhythmia, respectively. The management and diagnosis of CAD include different types of medications that are used nowadays for the treatment of this disease. The highlights of the present review focused on stent technology and its useful applications. Finally, we also addressed the benefits of the stent, and its potential complications, effectiveness, indication, and contraindication that play a significant role in the recovery of CAD disease.

How do beliefs and attitudes of people influence energy conservation behavior in Pakistan?

Policymakers in developing countries like Pakistan mostly ignore the behavioral aspects of climate change mitigation, whereas literature is also deficient in advocating evidence-based mitigation strategies. This study aims to analyze the impact of personality traits, social norms, and attitudes on energy conservation behavior. Face-to-face interviews of 361 households are conducted in the capital city of Pakistan using random sampling. According to the characteristics of the data, the ordered logistic regression model is applied. The results reveal that education and gender do not contribute significantly toward energy conservation. In contrast, the behavior is more influenced by convenient lifestyle, the number of vehicles, distance of residence from the workplace, income, perception of energy security, and availability of transport. Furthermore, knowledge about sustainability and age is also critical to influencing energy conservation behavior. Therefore, the study recommends using different mediums to enhance the knowledge base of households about energy conservation and environmental sustainability, aligning the urban planning in view of location choices and use of public transport.
