Mr. S, 64, has a history of posttraumatic stress disorder (PTSD), which has been well controlled for the past 15 years with cognitive-processing therapy and fluoxetine, 40 mg/d. However, over the past 6 weeks, Mr. S has experienced increased hypervigilance, nightmares, and flashbacks. He states that his primary care provider recommended an adjustment in pharmacotherapy to address this exacerbation of symptoms. Previous medication trials include sertraline, 200 mg/d, discontinued due to lack of perceived efficacy, and venlafaxine, 150 mg/d, discontinued due to increased blood pressure.
Mr. S’s medical history includes hypertension, dyslipidemia, and myocardial infarction (MI) 5 years ago. His family history includes sudden cardiac death (mother and father) and major depressive disorder (sister). His blood pressure is currently uncontrolled on lisinopril, 5 mg/d, and metoprolol succinate, 50 mg/d. Today, serial blood pressure readings measured approximately 180/90 mm Hg, with a pulse 50-60 beats per minute.
What is the next step in treating Mr. S’s hypertension and PTSD symptoms? Is there any evidence to support concomitant therapy?
PTSD is characterized by emotional and behavioral symptoms following exposure to a traumatic event. Its 12-month prevalence in the United States is estimated at 3.5%. Diagnostic criteria necessitate the presence of intrusive symptoms, persistent effortful avoidance of distressing trauma-related stimuli, negative cognitions or mood, and alterations in arousal and reactivity. PTSD negatively impacts social and occupational functioning.1
Studies have revealed a correlation between the presence of psychosocial factors, such as depression and anxiety, and the occurrence of cardiovascular events. The mechanism appears to consist of a behavioral component (eg, poor diet, tobacco use) and a direct pathophysiologic component (eg, excessive sympathetic nervous system activation) (Table 13).4 Management of concomitant PTSD and CVD presents a challenge to clinicians.
