Thanks for your question on Health Care Magic.
I can understand your concern.
Pulmonary embolism is common in old age due to
atherosclerosis and stiffening of arteries.
Severity, life expectancy, prognosis etc depends on
1. Size of embolism (massive embolism can cause sudden death).
2. Involvement of pulmonary artery. If
main Pulmonary artery is involved then prognosis is poor. But if distal, smaller arteries are involved then prognosis is good and hence life expectancy is more.
3. Severity of pulmonary
hypertension. Pulmonary embolism (PE) almost always cause Pulmonary hypertension (PH). So if PH is severe then prognosis is poor.
So please let me know these details, so that I can guide you more about life expectancy in your father's case.
Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
