What are the symptoms of cardiovascular and cerebrovascular diseases in the elderly?

Elderly patients with cardiovascular and cerebrovascular diseases may experience symptoms such as dizziness and blurred vision. Common manifestations include palpitations, shortness of breath, and chest tightness, which worsen with physical activity. They may also suffer from chest pain radiating to the left shoulder with numbness, frequent fatigue, weakness, and episodes of excessive sweating. During nighttime sleep, they often feel discomfort, suffocation, chest tightness, or occasional brief stabbing pains that usually disappear within one or two seconds.
