Final answer:
The upper age limit for cardiovascular tissue, with respect to disease onset, is generally more than 60 years old. Cardiovascular disease risk increases with age, influenced by various factors including sociopolitical contexts like the healthcare challenges faced by the LGBT youth.
Step-by-step explanation:
The upper age limit for cardiovascular tissue in the context of disease onset is largely associated with being more than 60 years old. On average, males tend to experience the onset of cardiovascular diseases about a decade before females. In fact, most cases of cardiovascular disease occur in individuals over the age of 60.
Additionally, while addressing the state of cardiovascular health across different populations, it's important to understand that the LGBT youth are considered at higher risk for cardiovascular diseases, as well as for conditions such as obesity, anxiety, and depression. This is partly because of the poor quality of care they might receive due to stigma and a lack of healthcare providers' awareness or insensitivity towards the unique needs of the LGBT community. Therefore, there is no strict upper age limit for the occurrence of cardiovascular tissue concerns, as pathology can be influenced by both age and other socioeconomic factors.
