SELECT T2.first, T2.last , CASE WHEN T2.deathdate IS NULL THEN strftime('%Y', T1.DATE) - strftime('%Y', T2.birthdate) ELSE strftime('%Y', T2.deathdate) - strftime('%Y', T2.birthdate) END AS age FROM observations AS T1 INNER JOIN patients AS T2 ON T1.PATIENT = T2.patient WHERE T1.DESCRIPTION = 'Systolic Blood Pressure' AND T1.VALUE = 200 AND T1.UNITS = 'mmHg' AND strftime('%Y', T1.DATE) = '2011'
