  Purpose

The fixed combination of verapamil SR/trandolapril (Tarka®) is an effective, well-tolerated therapy for the treatment of essential hypertension in those who require more than one agent to achieve optimal blood pressure (BP) control. The endpoint is compliance with Tarka® treatment by number/percentage of patients continued on fixed combination Tarka therapy after six months. This Post Marketing Observational Study will be conducted in a prospective, single-arm, single-country, multicenter format. The investigational sites will be the cardiologists, the doctors of internal medicine and general practicians. Since this will be a Post Marketing Observational Study, Tarka® will be prescribed in usual manner in accordance with the terms of the local market authorization with regards to dose, population and indication as well as the local guidelines.

Primary Outcome Measures:
  • Compliance With Tarka Treatment, All Participants and by Gender. [ Time Frame: Month 3 Visit ] [ Designated as safety issue: No ]
    Participants were asked how many doses of Tarka they had missed after three months of treatment.

  • Compliance With Tarka Treatment, All Participants and by Gender. [ Time Frame: Month 6 Visit ] [ Designated as safety issue: No ]
    Participants were asked how many doses of Tarka they had missed since their previous visit.


Secondary Outcome Measures:
  • Change in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP) [ Time Frame: Baseline to Month 6 Visit ] [ Designated as safety issue: No ]
    The mean (average) change in participants' systolic blood pressure and diastolic blood pressure from the baseline visit to the Month 6 visit.

  • Percentage of Patients Achieving Blood Pressure < 140/90 mmHg [ Time Frame: Month 3 Visit ] [ Designated as safety issue: No ]
    The percentage of patients who had achieved blood pressure less than 140/90 mmHg after three months of treatment.

  • Percentage of Patients Achieving Blood Pressure < 140/90 mmHg [ Time Frame: Month 6 Visit ] [ Designated as safety issue: No ]
    The percentage of patients who had achieved blood pressure less than 140/90 mmHg after six months of treatment.

  • Number and Type of Antihypertensive Drugs Added to Fixed Combination Tarka to Reach Blood Pressure Goal [ Time Frame: Month 3 Visit ] [ Designated as safety issue: No ]
    The number of participants at the Month 3 visit who were taking other antihypertensive drugs in addition to their Tarka treatment to reach blood a pressure goal of less than 140/90 mmHg. The number of participants taking each type of additional drug is summarized.

  • Number and Type of Antihypertensive Drugs Added to Fixed Combination Tarka to Reach Blood Pressure Goal [ Time Frame: Month 6 Visit ] [ Designated as safety issue: No ]
    The number of participants at the Month 6 visit who were taking other antihypertensive drugs in addition to their Tarka treatment to reach a blood pressure goal of less than 140/90 mmHg. The number of participants taking each type of additional drug is summarized.

  • Adverse Events Leading to Study Discontinuation [ Time Frame: Baseline to Month 6 Visit ] [ Designated as safety issue: No ]
    The number of participants who discontinued from the study due to an adverse event and reported event descriptions are summarized.

Groups/Cohorts
Czech patients with essential hypertension
Czech hypertensive patients (women and men) with systolic blood pressure (SBP) ≥ 140 mmHg or diastolic blood pressure (DBP) ≥ 90 mmHg who can be treated with fixed-combination Tarka®.

Detailed Description:

Follow-up of patients enables 4 patient visits during this period. For these reasons, the most likely visits are defined as "Inclusion visit" at which treatment with Tarka® is to be initiated, and then "Follow-up visit Week 4-6", "Follow-up visit Month 3 " and "Follow-up visit Month 6", although dates will depend only on the decision of the physician. For these reasons, the most likely visits are defined as "S/V" (Screening Visit), "F1" (Follow-up 1), "F2" (Follow-up 2), "F3" (Follow-up 3). The end point is compliance with Tarka® treatment by number/percentage of patients continued on fixed combination Tarka therapy after six months.
