PLASMA Mexico (PLASMA Mexico)

Study Overview
=================
Brief Summary
-----------------
Collect data on Mexican patients diagnosed with Heart Failure with reduced ejection fraction, their treatments, and their progress in a real-world environment. Additional objectives will be analyzed, such as mortality, the use of resources associated with the follow-up of this group of patients and the barriers, if any, to receiving the indicated treatment.

Detailed Description
-----------------
Identify the main epidemiological and clinical characteristics of patients with Heart Failure with reduced ejection fraction, as well as the medical treatment models used. Determine the prescription rate of a cardiovascular pharmacological treatment and the prescription and implant rate of a cardiac medical device in patients with Heart Failure with reduced ejection fraction. Determine the mortality rate and its classification in patients with Heart Failure with reduced ejection fraction. Identify the barriers, if any, to prescribing and implanting a cardiac medical device in those patients with a Class I recommendation according to the ACC/AHA/HRS 2017 guidelines. Determine the population with a profile of 1.5 primary prevention of sudden cardiac death (patients with Heart Failure in primary prevention who have one or more of the following risk factors: syncope or pre-syncope; left ventricular ejection fraction less than 25%; presence of non-sustained ventricular tachycardia; more than 10 ventricular extrasystoles per hour observed in a 24-hour Holter). Collect data on the use of resources associated with the follow-up of patients diagnosed with Heart Failure with reduced ejection fraction during a period of 12 months to perform a secondary economic analysis.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Identify the main epidemiological and clinical characteristics of patients with Heart Failure with reduced ejection fraction, as well as the medical treatment models used. | Patient´s baseline characteristics, medical history, socio-economic data, ancillary studies, laboratory tests, and cardiovascular medication will be summarized using summary statistics. Continuous variables will be presented using mean, standard deviation (SD), minimum, median, maximum, and interquartile range (IQR). Categorical variables will be presented as frequency and percentage. | 1 year | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Determine the prescription rate of a cardiovascular pharmacological treatment and the indication and implant rate of a cardiac medical device in patients with Heart Failure with reduced ejection fraction. | Number and percentage of cardiovascular medication prescription by type Number and percentage of patients with an indication for a cardiac medical device Number and percentage of patients referred for an implant of a cardiac medical device Number and percentage of patients who received an implant of a cardiac medical device | 1 year | 
| Determine the mortality rate and its classification in patients with Heart Failure with reduced ejection fraction. | Number and percentage of deaths during the study follow-up period Number and percentage of deaths according to their classification Risk assessment of sudden cardiac death in the population Risks comparison of sudden death at 6 and 12 months of follow-up | 1 year | 
| Identify the barriers, if any, to prescribing and implanting a cardiac medical device in those patients with a Class I recommendation according to the ACC/AHA/HRS 2017 guidelines. | Number and percentage of reasons for not indicating a cardiac medical device Number and percentage of reasons for not implanting a cardiac medical device | 1 year | 
| Determine the population with a profile of 1.5 primary prevention of sudden cardiac death | Number and frequency of patients with indication for 1.5 primary prevention of sudden cardiac death (patients with Heart Failure in primary prevention who have one or more of the following risk factors: syncope or pre-syncope; left ventricular ejection fraction less than 25%; presence of non-sustained ventricular tachycardia; more than 10 ventricular extrasystoles per hour observed in a 24-hour Holter) | 1 year | 
| Collect data on the use of resources associated with the follow-up of patients diagnosed with Heart Failure with reduced ejection fraction during a period of 12 months to perform a secondary economic analysis. | Analysis will include Continuous variables will be summarized using mean, SD, minimum, median, maximum, and IQR. Categorical variables will be summarized as number and percentage of total patients. Analysis of health resources of the population at 6 and 12 months will be made using Student's t test if they have a normal distribution, or a Mann-Whitney U test in case of a non-normal distribution. | 1 year |
