Your daily 6 km run is excellent for cardiovascular health; you do not need to change your exercise routine, but do ensure you have rest days. Since your blood pressure remains high at 145/90 despite this active lifestyle, genetics or other factors may be at play. Medication is likely necessary to lower your cardiovascular risk. Common first-line treatments include ACE inhibitors (e.g., Lisinopril) or ARBs (e.g., Losartan). However, medication must be tailored to your specific health profile. Please visit your doctor for a proper clinical evaluation and a personalised prescription. Do not self-medicate.
